摘要：ロータに磁石を有する交流電動機(MG1)と、コンバータ(120)と、インバータ(130)とを含むモータ駆動システム(100)のための制御装置(200)は、交流電動機(MG1)のトルク指令値に基づいて、コンバータ(120)に対する昇圧指令値を生成する。制御装置(200)は、昇圧指令値と交流電動機(MG1)の駆動状態に基づいて、インバータ(130)から交流電動機(MG1)へ供給する磁石の力を弱める方向の電流を増加する弱め界磁制御を実行すべきか否かを判定する。そして、制御装置(200)は、弱め界磁制御を実行すべき場合であって、かつトルク指令値の絶対値がしきい値よりも小さいときには、生成した昇圧指令値をさらに増加する。このようにすることによって、弱め界磁電流量を低減することができるので、モータ駆動システム(100)の効率を向上させることができる。

SOLUTION: A motor controller includes a voltage detecting circuit which detects an induced voltage at each phase of a motor by an analog signal and converts the result of detection into a digital signal, a PWM control circuit which carries out variable-speed control over the motor by adjusting a duty factor representing an on-time in a switching cycle of a switching element based on information of an induced voltage at a switching-off phase detected by the voltage detecting circuit, and a duty factor changing unit which changes a duty factor of the PWM control circuit based on a difference between a duty factor adjusted by the PWM control circuit and a predetermined duty factor. The PWM control circuit reads in a detection result from the voltage detecting circuit during an on-cycle of the switching element that is defined by a duty factor changed by the duty factor changing unit.
