To provide a motor control device and the like which can suppress deterioration in behavior of a rotation speed of a motor generator caused by switching control gain.SOLUTION: An MG-ECU functions as a motor control device that controls a motor generator connected to an engine. The MG-ECU performs feedback control so that a ration speed approaches a command value, using a rotation speed-detected value determined by detecting a rotation speed of the motor generator, so as to make the motor generator output damping torque having antiphase to torque variation of the engine. The MG-ECU switches control gain for the feedback control, between a plurality of control gain including low gain and high gain. In at least second transition DT, of first transition UT from the low gain to the high gain and the second transition DT from the high gain to the low gain, transition of non-linear gain is executed.SELECTED DRAWING: Figure 10

    【課題】制御ゲインの切り替えに伴う回転数の挙動の悪化を抑制可能なモータ制御装置等の提供。【解決手段】MG-ECUは、エンジンと接続されるモータジェネレータを制御するモータ制御装置として機能する。MG-ECUは、モータジェネレータの回転数を検出した回転数検出値を用いて、回転数が指令値に近づくようにフィードバック制御することで、エンジンのトルク変動に対し逆位相となる制振トルクをモータジェネレータに出力させる。MG-ECUは、フィードバック制御の制御ゲインを、低ゲイン及び高ゲインを含む複数のうちで切り替える。そして、低ゲインから高ゲインへの第1遷移UT、及び高ゲインから低ゲインへの第2遷移DTのうちで、少なくとも第2遷移DTにて、非線形のゲイン遷移が実施される。【選択図】図10
