[0047] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0048] Figure 1 A flow chart of a method for adjusting the motion mode of a detection device provided by an embodiment of the present invention. The method comprises the following steps:

[0049] Step 101, constructing a motion regulation model of the detection device; wherein the motion regulation model includes a motion capability mathematical model, a control performance mathematical model and an energy consumption level mathematical model.

[0050] The detection device involved in the present invention has a spherical appearance and is actually a spherical robot. It performs mobile detection based on a pendulum-type eccentric force driving mechanism, has low structural complexity and high driving efficiency.

[0051] A motion regulation model is constructed for the detection device of the spherical structure. There are two driving modes of the detection device of the spherical robot, namely, heavy pendulum drive and inverted pendulum drive.

[0052] The performance parameters of the detection device provided with a spherical structure of the present invention are shown in Table 1:

[0053]

[0054] Table 1 Performance parameters of detection equipment

[0055] The control performance mathematical model in the motion regulation model is determined by the control system convergence speed, control overshoot, control stability and control system response speed; the control performance mathematical model formula is expressed as:

[0056]

[0057] in, Indicates the speed of movement, It represents the convergence speed of the control system, which is related to the drive pendulum length and the climbing slope angle; Indicates the control overshoot, which is related to the movement speed, drive pendulum length and climbing slope angle; Indicates control stability, which is related to movement speed, drive pendulum length and climbing slope angle; It indicates the response speed of the control system and is related to the movement speed, drive pendulum length and climbing slope angle.

[0058] Specifically, by adjusting the pendulum length L, slope angle γ and expected speed v during the operation of the detection device of the spherical mechanism, it can be seen that in terms of controlling the convergence speed of the detection device, the change trend of the inverted pendulum drive mode is the same as that of the heavy pendulum drive mode, which becomes worse with the increase of the task slope or movement speed, and becomes better with the increase of the center of mass-center distance. Compared with the heavy pendulum drive mode, the inverted pendulum drive mode has a disadvantage in terms of the control system convergence speed, which can increase with the increase of the task slope or movement speed, and when the detection device of the spherical structure is in a horizontal plane motion state, the above disadvantage can remain relatively stable with the increase of the center of mass-center distance, and when the detection device of the spherical structure is in a slope motion state, the above disadvantage can be reduced with the increase of the center of mass-center distance.

[0059] Based on the above discussion, in the heavy pendulum driving mode and the inverted pendulum driving mode, the convergence speed level is expressed by the following formula:

[0060]

[0061] i is the driving mode number, i=1 is the heavy pendulum driving mode, and i=2 is the inverted pendulum driving mode.

[0062] (1) For different pendulum lengths L and desired speeds v d Combined, the convergence time t in two different modes r1 With t r2 The changing trend of Figure 2 As shown:

[0063] The pendulum length L and expected speed v of the spherical robot under two driving modes d When both remain consistent, 0.48s≤t r2 -t r1≤6.03s, that is, the inverted pendulum drive mode is inferior to the heavy pendulum drive mode in terms of convergence speed. d When the pendulum length L changes from 0.04m to 0.12m, the convergence speed of the two driving modes gradually accelerates. For further analysis, When v d When the speed is 0.2m / s, It changes randomly in a small range, with an average value of 111.50%; when v d Gradually increase from 0.2m / s to 1.6m / s, Changes randomly in a small range, with v d The average value of the change gradually increases to 129.38% compared with 0.2m / s, that is, in terms of convergence speed, the disadvantage of the inverted pendulum drive mode relative to the heavy pendulum drive mode remains relatively stable as the pendulum length L increases, and as the expected speed v d Increase and gradually increase.

[0064] Using the least squares method Figure 2 The experimental data shown in the figure are fitted by formula, and the decimal place of the coefficient to be determined is 2. Then the convergence time tri, the pendulum length L and the expected speed v d The mathematical model is shown in the following formula:

[0065]

[0066]

[0067] According to the theoretical error analysis method, the fitting accuracy is judged by the following formula:

[0068]

[0069] The fitting accuracy of the experimental data was judged according to the formula, and the fitting accuracy was 0.171s and 0.136s respectively, which did not affect the fitting accuracy of the experimental data.

[0070] (2) Combining different pendulum lengths L and slope angles γ, the convergence time t in two different modes r1 With t r2 The changing trend of Figure 3 As shown:

[0071] When the pendulum length L of the spherical robot and the slope angle γ are consistent in the two driving modes, 0.61s≤t r2 -t r1≤6.30s, that is, the inverted pendulum drive mode is inferior to the heavy pendulum drive mode in terms of convergence speed. When the slope angle γ is constant and the pendulum length L gradually changes from 0.04m to 0.12m, the convergence speeds of the two drive modes gradually increase. Further analysis shows that when γ is 1°, It gradually decreases, and its average value is 127.13%; when γ is 3°, gradually decreases, and its average value is 132.69%; as γ increases from 0° to 10°, The changing average value gradually increases from 120.40% to 142.71%, that is, in terms of convergence speed, the disadvantage of the inverted pendulum driving mode relative to the heavy pendulum driving mode gradually decreases with the increase of the pendulum length L, and gradually increases with the increase of the slope angle γ.

[0072] Using the least squares method Figure 3 The experimental data shown in the figure are fitted by formula, and the decimal place of the undetermined coefficient is 2. The mathematical model of the convergence time tri, the pendulum length L and the slope angle γ is as follows:

[0073]

[0074]

[0075] The fitting accuracy of the experimental data was judged according to the formula, and the fitting accuracy was 0.127s and 0.155s respectively, which did not affect the fitting accuracy of the experimental data.

[0076] (3) Combining different pendulum lengths L and slope angles γ, the convergence time t in two different modes r1 With t r2 The changing trend of Figure 4 As shown:

[0077] Through similar analysis as above, the least square method is used to Figure 4 The experimental data shown in the figure are fitted by formula, and the mathematical model of convergence time tri, pendulum length L and slope angle γ is as follows:

[0078]

[0079]

[0080] The fitting accuracy of the experimental data was judged according to the formula, and the fitting accuracy was 0.162s and 0.141s respectively, which did not affect the fitting accuracy of the experimental data.

[0081] Furthermore, by normalizing the above three sets of fitting formulas, we can get the formula for the convergence speed level. In the formula, given the pendulum length L and the expected speed vd And the actual value of the slope angle γ, we can get the control system convergence speed level in the two modes. The pendulum length L ranges from [0.04, 0.12]; v d The value range is [0.2,1.6]; the value range of γ corresponding to L is [0,10]. The range of variation is [0,1], and The smaller the value, the faster the convergence speed.

[0082] In terms of controlling overshoot, the changing trend of the inverted pendulum drive mode is the same as that of the heavy pendulum drive mode, that is, it becomes worse with the increase of the task slope or movement speed, and becomes better with the increase of the center of mass-center distance. Compared with the heavy pendulum drive mode, the inverted pendulum drive mode has an advantage in controlling overshoot, which can increase with the increase of the task slope or movement speed, and when the detection device is in a horizontal plane motion state, the above advantages can remain relatively stable with the increase of the center of mass-center distance, and when the detection device is in a slope motion state, the above advantages can decrease with the increase of the center of mass-center distance.

[0083] Based on the above discussion, in the heavy pendulum driving mode and the inverted pendulum driving mode, the control overshoot level is expressed by the following formula:

[0084]

[0085] (1) For different pendulum lengths L and desired speeds v d Combined, the maximum absolute value of the spherical shell motion position error in two different modes |e x | max1 and |e x | max2 , and the maximum absolute value of the swing position error |e x | max1 With |e x | max 2 , the changing trend is as follows Figure 5 As shown;

[0086] The pendulum length L and expected speed v of the spherical robot under two driving modes d When all remain consistent, 0.031m≤|e x | max1 -|e x | max2 ≤0.249m, 0.038rad≤|e α | max1 -|e α | max2 ≤0.195rad, that is, in terms of controlling overshoot, the inverted pendulum drive mode has an advantage over the heavy pendulum drive mode. dWhen the pendulum length L changes from 0.04m to 0.12m, the control overshoot of the two driving modes gradually decreases. Further analysis: When v d When it is 0.2m / s, It changes randomly in a small range, with an average value of 81.24%; when v d Gradually increase from 0.2m / s to 1.6m / s, Changes randomly in a small range, with v d The average value of the change gradually decreases to 67.35% compared with 0.2m / s, that is, in terms of controlling overshoot, the advantage of the inverted pendulum drive mode over the heavy pendulum drive mode remains relatively stable as the pendulum length L increases, and gradually increases as the desired speed vd increases.

[0087] Using the least squares method Figure 5 The experimental data is fitted by formula to obtain the maximum absolute value of the spherical shell motion position error when the motion does not converge |e x | max , pendulum length L and desired velocity v d Mathematical model and the maximum absolute value of the position error of the re-swing when the motion has not converged |e α | max , pendulum length L and desired velocity v d Mathematical model As shown below:

[0088]

[0089]

[0090]

[0091]

[0092] The fitting accuracy of the experimental data was judged to be 0.0124m, 0.0089m, 0.0103rad, and 0.0117rad, respectively. This fitting accuracy does not affect the trend judgment of the experimental data.

[0093] (2) For different combinations of pendulum length L and slope angle γ, the maximum absolute value of the spherical shell motion position error in two different modes |e x | max1 and |e x | max2 , and the maximum absolute value of the swing position error |e x | max1 With |e x |max 2 , the changing trend is as follows Figure 6 As shown;

[0094] When the pendulum length L of the spherical robot and the slope angle γ are consistent in the two driving modes, 0.023m≤e x | max1 -|e x | max2 ≤0.142m, 0.022rad≤|e α | max1 -|e α | max2 ≤0.235rad, that is, in terms of controlling overshoot, the inverted pendulum drive mode has an advantage over the heavy pendulum drive mode.

[0095] When the slope angle γ is constant and the pendulum length L gradually changes from 0.04m to 0.12m, the control overshoot of the two driving modes gradually decreases. Further analysis: When γ is 1°, gradually increases, and its average value is 77.30%; when γ is 3°, As γ increases from 0° to 10°, The changing average value gradually decreases from 84.71% to 64.39%, that is, in terms of controlling overshoot, the advantage of the inverted pendulum driving mode over the heavy pendulum driving mode gradually decreases with the increase of the pendulum length L, and gradually increases with the increase of the slope angle γ.

[0096] Using the least squares method Figure 6 The experimental data is fitted by formula to obtain the maximum absolute value of the spherical shell motion position error when the motion does not converge |e x | max , mathematical model of pendulum length L and slope angle γ and the maximum absolute value of the position error of the re-swing when the motion has not converged |e α | max , mathematical model of pendulum length L and slope angle γ As shown below:

[0097]

[0098]

[0099]

[0100]

[0101] The fitting accuracy of the experimental data was judged to be 0.0072m, 0.0101m, 0.0137rad, and 0.0105rad, respectively. This fitting accuracy does not affect the trend judgment of the experimental data.

[0102] Furthermore, by normalizing the above two sets of fitting formulas, we can get the formula for controlling overshoot. In the formula, given the pendulum length L and the desired speed v d And the actual value of the slope angle γ, the control overshoot level in the two modes can be obtained. The pendulum length L ranges from [0.04, 0.12]; v d The value range is [0.2,1.6]; the value range of γ corresponding to L is [0,10]. The range of variation is [0,1], and The smaller the value, the faster the convergence speed.

[0103] Based on the above discussion, in the heavy pendulum driving mode and the inverted pendulum driving mode, the control stability level is expressed by the following formula:

[0104]

[0105] (1) For different pendulum lengths L and desired speeds v d Combined, the root mean square error of the spherical shell motion position error in two different modes is e x-rmse1 and e x-rmse2 , and the root mean square error of the swing position error e α-rmse1 and e α-rmse2 The changing trend of Figure 7 shown.

[0106] The pendulum length L and expected speed v of the spherical robot under two driving modes d When all remain consistent, 0.109m≤e x-rmse2 -e x-rmse1 ≤1.721m, 0.026rad≤e α-rmse2 -e α-rmse1 ≤0.154rad, that is, in terms of the control stability of the spherical robot, the inverted pendulum drive mode is inferior to the heavy pendulum drive mode. d When the pendulum length L gradually changes from 0.04m to 0.12m, the control stability of the two driving modes gradually increases. Further analysis: When v d When it is 0.2m / s, It changes randomly in a small range, and the average value of the change is 118.17%; when vd gradually increases from 0.2m / s to 1.6m / s, Changes randomly in a small range, with vd Compared with 0.2 m / s, the average value of the change gradually increases to 154.97%, that is, in terms of the control stability of the spherical robot, the disadvantage of the inverted pendulum drive mode relative to the heavy pendulum drive mode can remain relatively stable as the pendulum length L increases, and as the expected speed v d gradually increases with the increase of .

[0107] Using the least squares method Figure 7 The experimental data is fitted by formula to obtain the root mean square error of the spherical shell motion position error when the motion does not converge. x-rmse , pendulum length L and desired velocity v d Mathematical model and the root mean square error of the swing position error when the motion has not converged e α-rmse , pendulum length L and desired velocity v d Mathematical model As shown below:

[0108]

[0109]

[0110]

[0111]

[0112] The fitting accuracy of the experimental data was judged to be 0.0207m, 0.0173m, 0.0054rad, and 0.0029rad, respectively. This fitting accuracy does not affect the trend judgment of the experimental data.

[0113] (2) The root mean square error of the spherical shell motion position error under two different modes is e for different combinations of pendulum length L and slope angle γ. x-rmse1 and e x-rmse2 , and the root mean square error of the swing position error e α-rmse1 and e α-rmse2 The changing trend of Figure 8 shown.

[0114] When the pendulum length L of the spherical robot and the slope angle γ are consistent in the two driving modes, 0.079m≤e x-rmse2 -e x-rmse1 ≤0.602m, 0.020rad≤e α-rmse2 -e α-rmse1 ≤0.149rad, that is, in terms of control stability, the inverted pendulum driving mode is inferior to the heavy pendulum driving mode. When the slope angle γ is constant and the pendulum length L gradually changes from 0.04m to 0.12m, the control stability of the two driving modes gradually decreases. Further analysis: When γ is 1°, It gradually decreases, and its average value is 129.47%; when γ is 3°, gradually decreases, and its average value is 138.28%; as γ increases from 0° to 10°, The changing average value gradually increases from 122.91% to 147.47%, that is, in terms of control stability, the disadvantage of the inverted pendulum driving mode relative to the heavy pendulum driving mode gradually decreases with the increase of the pendulum length L, and gradually increases with the increase of the slope angle γ.

[0115] Using the least squares method Figure 8 The experimental data is fitted by formula to obtain the root mean square error of the spherical shell motion position error when the motion does not converge. α-rmse , mathematical model of pendulum length L and slope angle γ and the root mean square error of the swing position error when the motion has not converged e α-rmse , mathematical model of pendulum length L and slope angle γ As shown below:

[0118]

[0119]

[0120] The fitting accuracy of the experimental data was judged to be 0.0236m, 0.0203m, 0.0091rad, and 0.0074rad, respectively. This fitting accuracy does not affect the trend judgment of the experimental data.

[0121] Furthermore, by normalizing the above two sets of fitting formulas, we can get the formula for control stability. In the formula, given the pendulum length L and the desired speed v d And the actual value of the slope angle γ, we can get the control stability level in the two modes. The pendulum length L ranges from [0.04, 0.12]; v d The value range is [0.2,1.6]; the value range of γ corresponding to L is [0,10]. The range of variation is [0,1], and The smaller the value, the faster the convergence speed.

[0122] Based on the above discussion, in the heavy pendulum driving mode and the inverted pendulum driving mode, the control system response speed level is expressed by the following formula:

[0123]

[0124] (1) For different pendulum lengths L and desired speeds v d Combined, the convergence time t in two different modes τ-max1 and t τ-max2 The changing trend of Fig. 9 shown.

[0125] The pendulum length L and expected speed v of the spherical robot under two driving modes d When all remain consistent, 0.10s≤t τ-max1 -t r-max2 ≤0.39s, that is, the inverted pendulum drive mode has an advantage over the heavy pendulum drive mode in terms of control system response speed. d When the pendulum length L gradually changes from 0.04m to 0.12m, the control system response speed of the two driving modes gradually decreases. Further analysis: different v d In case of In a small range of disordered changes, that is, in terms of control system response speed, the advantage of the inverted pendulum drive mode over the heavy pendulum drive mode increases with the pendulum length L and the desired speed v d Increased and remained relatively stable.

[0127]

[0128]

[0129] The fitting accuracy of the experimental data was judged to be 0.0137s and 0.0106s respectively, which did not affect the trend judgment of the experimental data.

[0130] (2) Combining different pendulum lengths L and slope angles γ, the convergence time t in two different modes τ-max1 and t τ-max2 The changing trend of Fig.10 shown.

[0131] When the pendulum length L of the spherical robot and the slope angle γ are consistent in the two driving modes, 0.12s≤t τ-max1 -t τ-max2≤0.32s, that is, the inverted pendulum drive mode has an advantage over the heavy pendulum drive mode in terms of control system response speed. When the slope angle γ is constant and the pendulum length L gradually changes from 0.04m to 0.12m, the control system response speeds of the two drive modes gradually decrease. Further analysis: In a small range of disordered changes, that is, in terms of control system response speed, the advantage of the inverted pendulum drive mode over the heavy pendulum drive mode remains relatively stable as the pendulum length L and the slope angle γ increase.

[0132] Using the least squares method Fig.10 The experimental data is fitted by formula, and the decimal place of the coefficient to be determined is 2, then the maximum torque generation time t τ-maxi , mathematical model of pendulum length L and slope angle γ As shown below:

[0133]

[0134]

[0135] The fitting accuracy of the experimental data was judged to be 0.127s and 0.155s respectively, which did not affect the trend judgment of the experimental data.

[0136] Furthermore, by normalizing the above two sets of fitting formulas, we can get the formula for control stability. In the formula, given the pendulum length L and the desired speed v d And the actual value of the slope angle γ, we can get the control stability level in the two modes. The pendulum length L ranges from [0.04, 0.12]; v d The value range is [0.2,1.6]; the value range of γ corresponding to L is [0,10]. The range of variation is [0,1], and The smaller the value, the faster the convergence speed.

[0137] The mathematical model formula of sports ability is expressed as:

[0138]

[0139] in, Indicates the climbing slope angle, A represents the driving pendulum length of the spherical structure detection device; Norm (L) represents the gradeability, which is related to the drive pendulum length; B Norm (L, γ) represents the steering ability, which is related to the drive pendulum length and the climbing slope angle; Norm is the normalization operation.

[0140] The correspondence between the pendulum length L and the maximum slope angle γ is as follows: Fig.11 As shown in the figure, when the movement of the spherical structure detection device can converge, the climbing ability of the device in the inverted pendulum drive mode and the heavy pendulum drive mode is the same. As the pendulum length L gradually changes from 0.04m to 0.12m, the maximum climbing angle gradually increases from 3° to 10°.

[0141] Using the least squares method Fig.10 Perform a formula fitting, and the decimal place of the undetermined coefficient is 2, then the mathematical model fitting results of the pendulum length L and the maximum climbing angle γ are as follows:

[0142] γ=A(L)=-10416.67L 3 +2857.14L 2 -152.98L+5.20

[0143] It can be seen that in terms of climbing ability, the inverted pendulum driving mode is the same as the heavy pendulum driving mode, and the climbing ability increases with the increase of the distance between the center of mass and the center of the ball.

[0144] The climbing ability of the spherical structure detection device in the heavy pendulum driving mode and the inverted pendulum driving mode is expressed by the following formula:

[0145] A Norm (L) = Norm[1 / A(L)]

[0146] Combining different pendulum lengths L and slope angles γ, the maximum distance D between the motion path and the line connecting the initial and target positions in two different modes max1 With D max2 The changing trend of Fig.12 shown.

[0147] In the two driving modes, when the pendulum length L and the slope angle are consistent, 0.061m≤D max1 -D max2 ≤0.219m, that is, the inverted pendulum driving mode has an advantage over the heavy pendulum driving mode in terms of steering ability. When the slope angle γ is constant and the pendulum length L gradually changes from 0.04m to 0.12m, the steering ability of the two driving modes is gradually enhanced. Further analysis: When γ is 0°, It changes randomly in a small range, and the average value is 83.33%; when γ is 1°, gradually increases, and the average value is 80.55%; when γ is 3°, gradually increases, with an average value of 76.06%; as γ increases from 0° to 10°, The changing average value decreases from 83.33% to 73.34%, that is, in terms of steering ability, the advantage of the inverted pendulum driving mode over the heavy pendulum driving mode gradually decreases with the increase of the pendulum length L, and also gradually decreases with the increase of the slope angle γ.

[0148] Using the least squares method Fig.12 Perform a formula fitting, and the decimal place of the coefficient to be determined is 2, then the maximum distance D between the motion path and the line connecting the initial and target positions max The mathematical model fitting results of the pendulum length L and the maximum climbing angle γ are as follows:

[0149] B (1) =-224.59L 3 +0.01γ 3 +85.44L 2 +0.01γ 2 -14.92L-0.03γ+1.85L 2 γ-0.02Lγ 2 -0.05Lγ+1.37

[0150] B (2) =-156.89L 3 -0.01γ 3 +61.45L 2 +0.01γ 2 -11.72L-0.08γ+0.22L 2 γ-0.02Lγ 2 +0.45Lγ+1.19

[0151] Based on the above, it can be seen that in terms of steering ability, the change trend of the inverted pendulum drive mode is the same as that of the heavy pendulum drive mode, that is, it becomes better with the increase of the task slope and the distance between the center of mass and the center of the ball. Compared with the heavy pendulum drive mode, the inverted pendulum drive mode has an advantage in the control system convergence speed, which can increase with the increase of the task slope, and when the spherical structure detection device is in a horizontal plane motion state, the above advantages can remain relatively stable with the increase of the distance between the center of mass and the center of the ball. When the spherical robot is in a slope motion state, the above advantages can decrease with the increase of the distance between the center of mass and the center of the ball.

[0152] The steering capability of the spherical structure detection device in the heavy pendulum driving mode and the inverted pendulum driving mode is expressed by the following formula:

[0153]

[0154] Given the pendulum length L and the desired velocity v d And the actual value of the slope angle γ, the steering ability level in the two modes can be obtained. The swing length L ranges from [0.04, 0.12]; vd The value range is [0.2,1.6]; the value range of γ corresponding to L is [0,10]. The range of variation is [0,1], and The smaller the value, the faster the convergence speed.

[0155] The energy consumption level mathematical model is determined by the average output power during the sampling period; the energy consumption level mathematical model formula is expressed as:

[0156]

[0157] in, It represents the average output power during the sampling period, which is related to the movement speed, drive pendulum length and climbing slope angle.

[0158] The energy consumption level evaluation index is the average power Pi output by the driving motor in each sampling period under two different driving modes. Its changes are analyzed and a relevant mathematical model is established.

[0159] (1) For different pendulum lengths L and desired speeds v d The change trends of the average output power P1 and P2 of the drive motor in each sampling period under the two different modes are as follows: Fig.13 shown.

[0160] Using the least squares method Fig.13 The experimental data shown in the figure are fitted by formula, and the decimal place of the coefficient to be determined is 2. Then the average output power Pi, pendulum length L and expected speed v of the drive motor in each sampling period are d Mathematical model As shown below:

[0161]

[0162]

[0163] The fitting accuracy of the experimental data was judged to be 0.013W and 0.021W respectively, which does not affect the trend judgment of the experimental data.

[0164] (2) For different combinations of pendulum length L and slope angle γ, the variation trends of the average output power P1 and P2 of the drive motor in each sampling period under two different modes are as follows: Fig.14 shown.

[0165] When the pendulum length L and the slope angle γ of the spherical robot are consistent in the two driving modes, 0.052W≤P1-P2≤0.936W, that is, the inverted pendulum driving mode has an advantage over the heavy pendulum driving mode in terms of energy consumption level. When the slope angle remains constant and the pendulum length L gradually changes from 0.04m to 0.12m, the energy consumption of the two driving modes increases. Further analysis: When γ is 1°, gradually increases, and its average value is 81.35%; when γ is 3°, As γ increases from 0° to 10°, The changing average value gradually decreases from 87.13% to 69.35%, that is, in terms of energy consumption level, the advantage of the inverted pendulum driving mode over the heavy pendulum driving mode gradually decreases with the increase of the pendulum length L, and gradually increases with the increase of the slope angle γ.

[0166] Using the least squares method Fig.14 The experimental data shown in the figure are fitted by formula, and the decimal place of the coefficient to be determined is 2. Then the mathematical model of the average output power Pi, pendulum length L and slope angle γ of the drive motor in each sampling period is As shown below:

[0167]

[0168]

[0169] The fitting accuracy of the experimental data was judged to be 0.024W and 0.018W respectively, which did not affect the trend judgment of the experimental data.

[0170] (3) For different combinations of pendulum length L and slope angle γ, the variation trends of the average output power P1 and P2 of the drive motor in each sampling period under two different modes are as follows: Fig.15 shown.

[0171] When the pendulum length L and the slope angle γ of the spherical robot are consistent in the two driving modes, 0.035W≤P1-P2≤1.482W, that is, the inverted pendulum driving mode has an advantage over the heavy pendulum driving mode in terms of energy consumption level. When the slope angle γ is constant and the pendulum length L gradually changes from 0.04m to 0.12m, the energy consumption of the two driving modes increases. Further analysis: When γ is 1°, gradually increases, and its average value is 86.04%; when γ is 3°, As γ increases from 0° to 10°, The changing average value gradually decreases from 91.35% to 73.33%, that is, in terms of energy consumption level, the advantage of the inverted pendulum driving mode over the heavy pendulum driving mode gradually decreases with the increase of the pendulum length L, and gradually increases with the increase of the slope angle γ.

[0172] Using the least squares method Fig.15 The experimental data shown in the figure are fitted by formula, and the decimal place of the coefficient to be determined is 2. Then the mathematical model of the average output power Pi, pendulum length L and slope angle γ of the drive motor in each sampling period is As shown below:

[0173]

[0174]

[0175] The energy consumption level of the inverted pendulum drive mode has the same trend as that of the heavy pendulum drive mode, that is, it increases with the increase of the task slope or movement speed and the increase of the distance between the center of mass and the center of the sphere. Compared with the heavy pendulum drive mode, the inverted pendulum drive mode has an advantage in energy consumption level, which can increase with the increase of the task slope or movement speed, and when the detection device is in a horizontal plane motion state, the above advantages can remain relatively stable with the increase of the distance between the center of mass and the center of the sphere, and when the detection device is in a slope motion state, the above advantages can decrease with the increase of the distance between the center of mass and the center of the sphere.

[0176] The energy consumption level of the spherical structure detection equipment in the heavy pendulum driving mode and the inverted pendulum driving mode is expressed by the following formula:

[0177]

[0178] Given the pendulum length L and the desired velocity v d And the actual value of the slope angle γ, the steering ability level in the two modes can be obtained. The swing length L ranges from [0.04, 0.12]; v d The value range is [0.2,1.6]; the value range of γ corresponding to L is [0,10]. The range of variation is [0,1], and The smaller the value, the faster the convergence speed.

[0179] The motion adjustment model formula of the detection device is expressed as:

[0180]

[0181]

[0182] Among them, n1, n2, and n3 are weight parameters set according to the actual requirements for motion capability, control performance, and energy consumption level during the execution of the detection equipment task, and n1+n2+n3=1.

[0183] Assuming that the maximum climbing ability of the prototype of the detection equipment used is 10° and the maximum movement speed is 4m / s, the corresponding relationship between the climbing ability of the detection equipment and the climbing ability γ of the actual spherical robot is: The corresponding relationship between the movement speed and the actual movement speed v of the spherical robot is: The maximum pendulum length and the minimum pendulum length are 0.12m and 0.04m respectively. n1, n2, and n3 are weight parameters set according to the actual requirements for motion capability, control performance, and energy consumption level during the execution of the detection equipment task. The larger the parameter value, the more important the related performance, and n1+n2+n3=1.

[0184] For a given The corresponding pendulum length value can be calculated by the model formula to obtain the optimal The optimal pendulum length of the spherical robot in actual use can be obtained by converting the following formula:

[0185]

[0186] Therefore, in the mission preparation stage, the detection equipment with a spherical structure with a radially variable center of mass can select the driving mode according to the motion characteristics of the two driving modes and the actual requirements of the mission, and during the mission execution, the optimal pendulum length L can be determined and adjusted according to the mission's requirements for motion characteristics, the slope γ that needs to be faced, and the required motion speed v, so that the practicality of the spherical structure detection equipment in the face of unstructured mission environments is greatly improved.

[0187] Step 102, according to the real-time motion mode of the detection device, adjust the weight parameters corresponding to the motion ability mathematical model, the control performance mathematical model and / or the energy consumption level mathematical model in the motion adjustment model to adjust the motion mode of the detection device.

[0188] In the embodiment of the present invention, the current slope angle γ is set to 0°, and the expected speed v d Set to 1m / s.

[0189] Task 1: If the spherical detection equipment needs to have the best energy consumption performance during the task execution, adjust n1, n2, and n3 in the motion regulation model formula according to the task requirements, set the motion ability weight parameter n1 to 0.1, the control performance weight parameter n2 to 0.2, and the energy consumption level weight parameter n3 to 0.7.

[0190] Task 2: If the spherical robot needs to have a small control overshoot and at the same time ensure optimal control performance while taking into account energy consumption level performance, adjust n1, n2, and n3 in the motion regulation model formula according to task requirements, set the motion ability weight parameter n1 to 0.1, the control performance weight parameter n2 to 0.6, and the energy consumption level weight parameter n3 to 0.3.

[0191] According to the characteristics of the heavy pendulum drive and the inverted pendulum drive, compared with the heavy pendulum drive mode, the inverted pendulum drive mode has advantages in energy consumption level and control system overshoot. Therefore, the drive mode parameter in the model formula is set to 2 in both Task 1 and Task 2. Further calculation shows that the optimal pendulum length of Task 1 is L = 0.053m, and the optimal pendulum length of Task 2 is L = 0.098m.

[0192] Task 1 requires optimal energy consumption performance. The average output power of the drive motor in each sampling period is compared. Compared with the pendulum length L=0.12m in the heavy pendulum drive mode, the power reduction of the detection equipment in the heavy pendulum drive mode is 54.67% when the pendulum length is L=0.053m, and the power reduction in the inverted pendulum drive mode is 67.03%. It can be seen that the energy consumption performance is greatly improved.

[0193] Task 2 requires a small overshoot and a balanced energy consumption while ensuring optimal control performance. Therefore, the convergence time t r , the maximum absolute value of the position error when the motion does not converge |e x | max With |e α | max , the root mean square error of the position error when the motion does not converge e x-rmse With e α-rmse , the time when the maximum torque is generated during the movement τ-max The four types of control performance indicators and the average output power P of the drive motor in each sampling period are compared. Compared with the pendulum length L = 0.12m in the heavy swing drive mode, when the pendulum length is L = 0.098m, the detection device is in the heavy swing drive mode, and the average improvement of the four types of control performance indicators is 40.75%, while the indicator P decreases by 19.35%; when it is in the inverted pendulum drive mode, the average improvement of the four types of control performance indicators is 40.60%, while the indicator P decreases by 40.28%. The above data show that compared with the pendulum length L = 0.12m in the heavy swing drive mode, when the detection device is in the inverted pendulum drive mode and the pendulum length L = 0.098m, the control performance decreases but the energy consumption performance is improved.
