| description | To provide a control device for a rotary electric machine capable of suppressing a variation in responsiveness of a rotation speed due to a difference in a rotating body and improving productivity of a system.SOLUTION: A control device 40 calculates a feedback operation amount for controlling a rotation speed of a motor 20 on which a cooling fan 12 is mounted to a target value. Additionally, a load operation amount that is a feedforward operation amount corresponding to a load torque that increases as the rotation speed of the motor 20 increases is calculated based on the rotation speed. Then, an inverter 30 is operated based on a command operation amount that is a value obtained by adding the load operation amount to the feedback operation amount.SELECTED DRAWING: Figure 1
【課題】回転体の差異に伴う回転速度の応答性のばらつきを抑制し、かつシステムの生産性を向上させることができる回転電機の制御装置を提供することを目的とする。【解決手段】制御装置４０は、冷却用ファン１２が取り付けられたモータ２０の回転速度を目標値に制御するためのフィードバック操作量を算出する。また、回転速度に基づいて、モータ２０の回転速度が大きいほど大きな値となる負荷トルクに相当するフィードフォワード操作量である負荷操作量を算出する。そして、フィードバック操作量に、負荷操作量を加算した値である指令操作量に基づいて、インバータ３０を操作する。【選択図】 図１ |
