Example Embodiment
[0026] Embodiment 1.
[0027] figure 1 It is a block diagram showing the overall configuration of the motor control device according to Embodiment 1 of the present invention. The motor control device 101 is set based on the speed command vr which is an operation command input from the outside, the operation (speed) vm of the motor 1 detected by using a motion detector such as an encoder (not shown), and an input from the outside The response parameter Pr of the motor 1 causes the motor 1 to generate torque (driving force) τm in such a way that the operation of the motor 1 follows the operation command. In addition, the motor 1 drives a mechanical system 3 composed of the motor 1 and a mechanical load 2 coupled with the motor 1 by generating a torque τm. In addition, the motor 1 will be referred to as a rotary type motor and the term of a rotary system such as torque will be used. However, the motor 1 is not particularly limited to a rotary type, and may be a linear motor that ge...
Example Embodiment
[0096] Implementation mode 2.
[0097] In the first embodiment, the feedback filter 104 is configured to be twice, but even if it is more simply set to once, it is possible to realize a motor control device that obtains a similar effect. Image 6 It is a configuration diagram of the motor control device of the second embodiment. In addition, the configuration of the motor control device 201 of the second embodiment is the same as that of the first embodiment except for the control constant setting unit 205 and the control calculation unit 202. The same reference numerals are attached to the same components as those in the first embodiment, and the description thereof will be omitted.
[0098] The control calculation unit 202 includes an amplification compensation unit 103 and a feedback filter 204. The feedback filter 204 is a configuration in which the secondary feedback filter 104 in the first embodiment is changed to a primary filter. Regarding the control constant setting uni...

[0123] Implementation mode 3.
[0124] Picture 9 It is a block diagram showing the structure of a motor control device according to Embodiment 3 of the present invention. The configuration of the motor control device 301 according to the third embodiment is the same as that of the first embodiment except for the control constant setting unit 305 and the control calculation unit 302. The same reference numerals are attached to the same components as those in the first embodiment, and the description thereof will be omitted.
[0125] In the first embodiment, the feedback filter 104 in the control arithmetic unit 102 outputs the torque command τr with the output of the amplifying and compensating unit 103 as an input. In contrast, in the third embodiment, the feedback filter in the control arithmetic unit 302 The detector 304 takes the detection speed vb as an input, and outputs the filter speed vbf as an intermediate variable in the control calculation unit 302.
