| description | PROBLEM TO BE SOLVED: To provide a power steering device controller that is capable of reducing electromagnetic noises through spectrum diffusion and realizing stable motor control, and a power steering device using the same.SOLUTION: A control period is not fixed, and one cycle of the control period is the integral multiple of a carrier cycle. In order to prevent controllability from being lost even when the control period changes, calculation for determining the carrier cycle of a next control period is executed before a voltage command value is calculated, the voltage command value being the output of a voltage command value calculation unit regarding a current control period, and a control amount and a parameter are updated for each motor control period according to changes in last, current and next control periods.SELECTED DRAWING: Figure 1
【課題】スペクトラム拡散により電磁ノイズが低減でき、安定したモータ制御を実現できる、パワーステアリング装置の制御装置、及びそれを用いたパワーステアリング装置を提供することを目的とする。【解決手段】制御周期は一定とせずキャリア周期の整数倍で制御周期の1周期とする。そして、制御周期が変化しても制御性を損なわないようにするために、次の制御周期のキャリア周期を決める演算を現在の制御周期の電圧指令値演算部の出力である電圧指令値が演算されるよりも前に実施することとし、前回と現在と次の制御周期の変化に合わせて操作量とパラメータをモータ制御周期毎に更新することとした。【選択図】図１ |
