<P>PROBLEM TO BE SOLVED: To provide a torque controller for a motor capable of suppressing a periodic disturbance of torque output of a motor and a mechanical resonance thereof in a motor controller, such as a torque vibrator, for causing a motor to generate a torque output having an arbitrary waveform. <P>SOLUTION: The torque controller for motor executes current vector control on the basis of a torque command value T<SP>*</SP>in a motor 13 for driving a load device 14, and corrects a torque command value by a periodic disturbance compensation current table 19 for suppressing the periodic disturbance of torque output of the motor. In the controller, a resonant phenomenon of an electric machine system due to the frequency component of the torque output is identified as a system transmission function for each frequency component from the torque command value to a torque detection value Tdet, and a torque command value is generated by a resonance suppressing table 21 using an inverse number of an identification result for each frequency component. <P>COPYRIGHT: (C)2011,JPO&INPIT |
