Adjusting the model parameters through experimental data can improve the prediction accuracy of the model.

[0028] S103 . Based on the excitation simulation model, the displacement signal and the acceleration signal are processed to determine the excitation coupling interference signal.

[0029] In the embodiment of the present invention, the above-mentioned excitation coupling interference signal can be an unexpected or undesigned signal generated when multiple excitation sources (such as electro-hydraulic and electromagnetic exciters) interact with each other. This interference usually occurs when the vibration effects of different exciters in the excitation system overlap or interfere with each other. Specifically, the characteristics and effects of the coupling interference can be determined by analyzing the displacement signal and acceleration signal obtained from the experiment and applying signal processing technology.

[0030] S104, adjusting and controlling the excitation simulation model according to the excitation coupling interference signal.

[0031] In a possible embodiment, by confirming the characteristics of the excitation coupling interference signal and its impact on the test object, corresponding control adjustment parameters are generated to adjust the output power of the electromagnetic-electro-hydraulic excitation system, thereby controlling the output stability of the electromagnetic-electro-hydraulic excitation system.

[0032] In an embodiment of the present invention, the excitation data of the exciter is obtained, and the excitation data includes a displacement signal and an acceleration signal; an excitation simulation model is determined; based on the excitation simulation model, the displacement signal and the acceleration signal are processed to determine the excitation coupling interference signal; and the excitation simulation model is adjusted and controlled according to the excitation coupling interference signal. Through the above method, by identifying the model parameters, a system model including an electro-hydraulic and electromagnetic exciter is accurately established, the stiffness, damping and coupling coefficient of the model are obtained, and the displacement and acceleration signals collected from the sensor are used to calculate and analyze the coupling interference signal transmitted from one excitation system to another, and finally these interferences are effectively eliminated or minimized through the designed anti-disturbance controller.

[0033] Optionally, the step of obtaining excitation data of the exciter, wherein the excitation data includes a displacement signal and an acceleration signal, further includes: detecting the exciter by a displacement sensor to obtain a displacement signal; and detecting the exciter by an acceleration sensor to obtain an acceleration signal.

[0034] In an embodiment of the present invention, depending on the different selections of the above-mentioned exciters, the boundaries of the exciters can be analyzed by a structural decoupling device consisting of three groups of transverse guide rails and three groups of vertical guide rails, wherein the electro-hydraulic exciter is connected to the excitation platform through three groups of vertical sliding guide rails; the electromagnetic exciter is connected to the excitation platform through three groups of transverse guide rails.

[0035] Specifically, the connected guide rails may be detected by using sensors in different connection methods to obtain corresponding signals.

[0036] More specifically, the displacement sensor may include, but is not limited to, a linear variable differential transformer (LVDT), a laser displacement sensor, a potentiometer, or other instrument for measuring the distance a component moves from a reference position.

[0037] The acceleration sensor can obtain an acceleration signal by measuring the rate of change of velocity over time.

[0038] In a possible embodiment, the displacement signal and acceleration signal of the exciter are detected and acquired through sensors corresponding to the guide rails arranged in horizontal and vertical modes.

[0039] Optionally, the step of determining the excitation simulation model further includes determining a target simulation model from among the electro-hydraulic-electromagnetic excitation simulation model, the electro-hydraulic excitation simulation model and the electromagnetic excitation simulation model based on preset simulation requirements.

[0040] In an embodiment of the present invention, the above-mentioned preset simulation requirements may be a series of goals and conditions set before establishing an electro-hydraulic-electromagnetic excitation simulation model, an electro-hydraulic excitation simulation model or an electromagnetic excitation simulation model to ensure the simulation effect and the accuracy of the test data.

[0041] Specifically, the selection can be based on frequency and amplitude requirements, interference control requirements, environmental conditions, test accuracy and data processing. Among them, the frequency range and amplitude requirements of vibration need to be clarified according to the target simulation requirements. For example, low-frequency and large-scale vibration is suitable for electro-hydraulic exciters, while high-frequency and fine vibration is suitable for electromagnetic exciters. If both low-frequency and high-frequency vibrations need to be taken into account, the electro-hydraulic-electromagnetic dual-axis excitation system is more suitable; in order to ensure the accuracy of the test, the interference suppression requirements of the decoupling control strategy need to be set in advance. The displacement and acceleration signals can be processed through the excitation simulation model to identify and suppress the coupling interference signals of the electro-hydraulic and electromagnetic excitation systems; the simulation requirements may require the system to operate under specific environmental conditions, such as high temperature, low temperature or humidity changes, which directly affects the applicability of the model. For example, the stability of the electro-hydraulic system at extreme temperatures may be different from that of the electromagnetic system, which requires the model to adapt to environmental constraints; in order to obtain high-precision vibration data, the requirements for data acquisition, processing and analysis of displacement and acceleration signals can be clarified in the requirements to ensure that the decoupling control can provide accurate feedback adjustment.

[0042] Optionally, in the step of processing the displacement signal and the acceleration signal based on the excitation simulation model to determine the excitation coupling interference signal, it also includes determining the system dynamics model corresponding to the excitation simulation model; based on the system dynamics model, processing the displacement signal and the acceleration signal to determine the excitation coupling interference signal.

[0043] In the embodiment of the present invention, the system dynamics model can be selected from three types: an electro-hydraulic exciter, an electromagnetic exciter, and an electro-hydraulic-electromagnetic exciter. Specifically, when an electro-hydraulic-electromagnetic exciter is used, the electro-hydraulic-electromagnetic system dynamics model can be determined by the following formula: ; Among them, m1 is the mass of the test object (including fixed tooling); m2 is the mass of the excitation platform; k1 is the connection stiffness between the electro-hydraulic exciter and the excitation platform; k2 is the connection stiffness between the electromagnetic exciter and the excitation platform; c1 is the connection damping between the electro-hydraulic exciter and the excitation platform; c2 is the connection damping between the electromagnetic exciter and the excitation platform; x1 is the vertical displacement response of the excitation platform and the test object; y1 is the horizontal displacement response of the excitation platform and the test object; fy is the sliding friction between the electro-hydraulic exciter and the excitation platform; fx is the sliding friction between the electromagnetic exciter and the excitation platform; x is the output displacement signal of the electromagnetic exciter, and y is the output displacement signal of the electro-hydraulic exciter.

[0044] ; Where μ is the sliding friction coefficient.

[0045] The above formula can be used to calculate and determine the system dynamics model of the electro-hydraulic-electromagnetic excitation system.

[0046] When only the electro-hydraulic exciter is used, the electro-hydraulic system dynamics model can be determined by the following formula: ; In an embodiment of the present invention, a system dynamics model corresponding to a comprehensive electro-hydraulic-electromagnetic excitation simulation model is determined according to preset simulation requirements. The model integrates the dynamic characteristics of the electro-hydraulic and electromagnetic exciters, such as stiffness, damping and mass parameters. Through the system dynamics model, advanced signal processing technology is used to analyze the collected displacement signals and acceleration signals, and then the coupling interference signals caused by the interaction between the electro-hydraulic and electromagnetic exciters are accurately identified. The processed data is used to adjust and optimize the control strategy of the excitation system to reduce or eliminate the impact of coupling interference.

[0047] The above method improves the accuracy and reliability of vibration testing and enhances the adaptability of the test system to complex vibration environments. By dynamically adjusting the excitation control parameters, the performance stability and safety in the excitation environment can be effectively improved.

[0048] Optionally, before the step of processing the displacement signal and the acceleration signal based on the system dynamics model to determine the excitation coupling interference signal, it also includes determining the placement method of the simulation object, the placement methods include fixed placement and direct placement; based on the placement method of the simulation object, determine the system dynamics model.

[0049] In an embodiment of the present invention, for a system dynamics model using only an electromagnetic exciter, the corresponding system dynamics model using only an electromagnetic exciter can be determined according to the placement method of the simulation object. Specifically, the above placement method can include but is not limited to fixed placement and direct placement.

[0050] When the placement method is fixed placement, the corresponding system dynamics model using only the electromagnetic exciter is: ; When the placement method is direct placement, the corresponding system dynamics model using only the electromagnetic exciter is:

[0051] Where x1≥x2≥0, or 0≥x1≥x2, or x1≥0 and x2≤0

[0052] Among them, x2≥x1>0, or 0>x2≥x1, or x2>0 and x1<0, k3 and c3 are the connection stiffness and damping between the excitation platform and the test object.

[0053] Through the above formula, the system dynamics model using only electromagnetic exciters can be determined according to the placement method.

[0054] Optionally, in the steps before processing the displacement signal and the acceleration signal based on the system dynamics model to determine the excitation coupling interference signal, it also includes determining the stiffness and damping parameters corresponding to the system dynamics model; decoupling the stiffness and damping parameters to determine the acceleration response function of the corresponding system; processing the acceleration response function according to a preset error function to obtain a corresponding response signal.

[0055] In the embodiment of the present invention, the stiffness may be the ability to resist deformation of an object, and is generally used to indicate the proportional relationship between force and displacement. The greater the stiffness, the better the ability to resist deformation.

[0056] The above damping parameters may refer to the property of the gradual energy loss of an object during movement in an excitation environment. The vibration amplitude in the excitation system can be reduced and the time it takes for the system to reach equilibrium can be prolonged based on the damping parameters. Generally speaking, the damping parameters can be used to predict and control the response behavior of the system after an external disturbance.

[0057] The above decoupling process can be performed according to the following steps: Will Changes to ; By decoupling the above equation, we can get the expression S of the vibration acceleration response function of the excitation platform: ; Determine the preset error function: ; in, is the relevant response signal in the dynamic model of the electro-hydraulic-electromagnetic excitation system , ; n is the number of test data.

[0058] According to the parameter vector with the minimum error function The dynamic model of the above system is learned, and the parameter vector of the above fitness error function is adjusted by the learned dynamic model. By finding the partial differential and setting it to 0, we can find the value of each element in the parameter vector that satisfies the preset error function to be the minimum. Similarly, we can solve k3 and c3.

[0059] The acceleration response function can be used to predict the change in system acceleration under a given external excitation based on the physical parameters of the system (such as mass, stiffness, and damping).

[0060] The above-mentioned response signal may refer to an output signal of the system under external stimulation.

[0061] The above-mentioned decoupling process can be to decompose a multivariable system (the variables in the system are interdependent) into several single variable systems (the variables are independent of each other), so that each subsystem can be analyzed and controlled independently.

[0062] In a possible embodiment, the mathematical model of a complex system can be simplified through the above decoupling process, so as to facilitate accurate dynamic analysis and design.

[0063] Optionally, in the step of processing the displacement signal and the acceleration signal based on the system dynamics model to determine the excitation coupling interference signal, it also includes calculating the response signal and the parameters corresponding to the system dynamics model to obtain the excitation coupling interference signal corresponding to the current system dynamics model.

[0064] In an embodiment of the present invention, the excitation coupling interference signal can be obtained according to the following formula: ; It is also possible to combine the coupling interference between the outside world and the system for calculation. The steps are as follows: Convert the excitation simulation model into the state space equation ; in, They are the matrices after the system model is converted into state space equations.

[0065] The interference signal of the coupling effect added by the electromagnetic excitation system to the electro-hydraulic excitation system and the interference signal of the coupling effect added by the electro-hydraulic excitation system to the electromagnetic excitation system are solved according to the response signal, and they are synthesized with the random noise interference signal to form the total unknown disturbance impedance signal.

[0066] A linear extended state observer (LESO) is designed to consider the total disturbance as a whole and estimate the total unknown disturbance signal in real time.

[0067]

[0068] In the formula, for The corresponding state quantity of the observer; L is the observer error feedback gain matrix.

[0069] Solve the control signal input to the system by the final controller, which can be expressed as:

[0070] In the formula, is the total disturbance estimated by the observer; b0 is an adjustable parameter.

[0071] When only an electro-hydraulic exciter is used for the excitation system or only an electromagnetic exciter is used for the excitation system, the excitation coupling interference signal calculation method of the present embodiment is used to design an auto-disturbance rejection controller.
