PROBLEM TO BE SOLVED: To provide a power controller which prevents interference even if single system drive and double system drive are switched, by interposing such a filter that transfer function properties of the single system drive and the double system drive become equal when controlling drive of a motor including two system coils with two control sections each including a motor counter electromotive voltage compensation function, and an electrically-driven power steering device which improves a steering feeling.SOLUTION: A motor controller comprises control sections 1 and 2 each for controlling driving of a motor including two system coils for each of the two system coils. The control sections 1 and 2 control driving of the motor under current feedback control based on a current command value and compensate for a motor counter electromotive voltage in accordance with a counter electromotive voltage compensation signal based on a motor angle or a motor angular velocity. In each path for compensating for the motor counter electromotive voltage, an LPF for noise cancellation is provided and in a feedback path, an angle feedback filter with which transfer function properties of the single system drive and the double system drive become equal is provided.SELECTED DRAWING: Figure 13
【課題】2系統巻線を有するモータを、モータ逆起電圧補償機能を有する2つの制御部で駆動制御する場合、片系統駆動と両系統駆動で同一の伝達関数特性となるようなフィルタを制御系に介挿することで、片系統駆動と両系統駆動を切り換えても干渉することのないモータ制御装置を提供すると共に、操舵フィーリングを向上した電動パワーステアリング装置を提供する。【解決手段】2系統巻線を有するモータを2系統巻線毎に駆動制御する制御部1及び2を備え、制御部1及び2はそれぞれ、電流指令値に基づく電流フィードバック制御でモータを駆動制御すると共に、モータ角度若しくはモータ角速度に基づく逆起電圧補償信号によりモータ逆起電圧の補償を行うモータ制御装置において、モータ逆起電圧を補償する経路にそれぞれノイズ除去用のLPFが設けられていると共に、片系統駆動及び両系統駆動で同一の伝達関数特性となる角度フィードバックフィルタをフィードバック経路に設ける。【選択図】図13
