摘要: A motor controller for an electric vehicle sufficiently reduces vibration components caused by torque ripples passing through a resonance frequency of body. The includes setting means generating first command, based on information, rotation position detection detecting the motor, speed calculation calculating from signal, high-pass filter that extracts AC signal component and suppression gain circuit outputs signal. in which is added to or subtracted command used as second so perform drive control motor.
