Abstract:	本文主要介紹一種三相同步座標軸電流控制的方法，此方法與傳統的同步座標軸電流控制的最大差別在於它加上了 Emf 電壓解耦以及電流命令前饋等兩項補償。由於感應馬達在利用複數向量的方法分析之後，可以表示成一類似直流馬達具有 Emf 和線圈電阻耦合的模式。因此若將這兩個電壓在同步座標軸解耦，則可設計出一高性能的三相交流電流控制器。理論上此控制器可達到在任何輸出頻率下電流振幅與相位誤差皆為零的性能。又因為此電流控制器完全以軟體方法實現，故易於維護與調整，且可配合自動參數調適以實現高性能全數位式驅動器。A synchronous frame current regulator with voltage compensation to eliminate the steady state current error is presented in this paper. Two compensations are added to the voltage command, one is to decouple the Emf voltage of the motor, and the other is to compensate for the stator resistance and leakage losses. In theory, the current regulator can achieve zero magnitude and phase error at any excitation frequency and load. Both the theoretical analysis and the experimental verifications are performed to verify the control scheme.
