Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
Document Type and Number:
Japanese Patent JP2023136660
Kind Code:
A
Abstract:
To provide a motor control device and a motor control method that achieve good speed and position control while suppressing torsional vibration of a shaft even when there is an error in a parameter to be controlled etc. in a controller.SOLUTION: A controller 100A that controls a control target 200 that can be regarded as a two-inertial system includes: a PI control unit 102 that generates a torque (torque command) T so that motor speed vm matches a motor speed command vm*; an FF torque generation unit 104 that calculates an FF torque Tff based on a speed command v*; a torsional torque target value generation unit 105 that calculates an ideal torsional torque target value Ttor* when the FF torque Tff is applied to a motor; ans addition/subtraction means 123 for multiplying a deviation between the torsion torque target value Ttor* and a torsion torque actual value Ttor from the control target 200 by FB gain G, and adding the result and the FF torque Tff to an output of the PI control unit 102 to calculate a torque T.SELECTED DRAWING: Figure 1
