To effectively suppress vibration and noise generated in a permanent magnet synchronous motor.SOLUTION: A motor control device 1 is provided with: a current command generation section 11 for generating a d-axis current command Id1* and a q-axis current command Iq1*; a current control section 14 for generating a d-axis voltage command Vd* and a q-axis voltage command Vq* on the basis of the d-axis current command Id1* and the q-axis current command Iq1*; a gate signal generation section 18 for generating gate signals for controlling the operation of an inverter on the basis of the d-axis voltage command Vd* and the q-axis voltage command Vq*; and a current command compensation section 12 for superimposing pulses on a d-axis current command Id1* and a q-axis current command Iq1* to compensate the d-axis current command Id1* and the q-axis current command Iq1*. The current command compensation section 12 changes each of amplitude and phase of pulses on the basis of a motor revolution speed.SELECTED DRAWING: Figure 2

    【課題】永久磁石同期モータで発生する振動や騒音を効果的に抑制する。【解決手段】モータ制御装置1は、d軸電流指令Id1*およびq軸電流指令Iq1*を生成する電流指令生成部11と、d軸電流指令Id1*およびq軸電流指令Iq1*に基づいてd軸電圧指令Vd*およびq軸電圧指令Vq*を生成する電流制御部14と、d軸電圧指令Vd*およびq軸電圧指令Vq*に基づいてインバータの動作を制御するためのゲート信号を生成するゲート信号生成部18と、d軸電流指令Id1*およびq軸電流指令Iq1*に脈動を重畳してd軸電流指令Id1*およびq軸電流指令Iq1*を補正する電流指令補正部12とを備える。電流指令補正部12は、モータの回転数に基づいて脈動の振幅および位相をそれぞれ変化させる。【選択図】図2
