| description | PROBLEM TO BE SOLVED: To improve the following of a primary magnetic flux with respect to a change in the primary magnetic flux command value.SOLUTION: A motor controller 1 has a coordinate conversion part 101; a first calculation part 102; and a coordinate conversion part 104. The coordinate conversion part 101 converts three-phase current[I] into an armature current[i] on a δc-γc rotation coordinate system for performing a primary magnetic flux control. The first calculation part 102 obtains the voltage command value[v*] on the δc-γc rotation coordinate system. The coordinate conversion part 104 coordinate-converts the voltage command value[v*] into a voltage command value[V*] on another coordinate system of the voltage applied to a rotary motor 3. When the first calculation part 102 obtains the voltage command value[v*], the first calculation part 102 calculates the voltage command value[v*] with a transient term corresponding to a change in the primary magnetic flux command value.
【課題】一次磁束指令値の変動に対する一次磁束の追従を向上させる。【解決手段】電動機制御装置１は、座標変換部１０１、第１計算部１０２、座標変換部１０４を備えている。座標変換部１０１は、三相電流［Ｉ］を、一次磁束制御を行うδｃ−γｃ回転座標系における電機子電流［ｉ］に変換する。第１計算部１０２はδｃ−γｃ回転座標系における電圧指令値［ｖ＊］を求める。座標変換部１０４は、電圧指令値［ｖ＊］を座標変換して、回転電動機３に印加する電圧の他の座標系における電圧指令値［Ｖ＊］へ変換する。第１計算部１０２は電圧指令値［ｖ＊］を求めるとき、一次磁束指令値の変動に応じた過渡項を盛り込んで計算する。【選択図】図１ |
