Abstract:	本文的目的在報告國科會的專題計畫電力電子推動小組：高性能交流馬達驅動器之分析、控制、量測與製作 (I)- 子計畫三：無量測器向量控制電機之弱磁與最佳效率控制第一年度之研究概況。主要針對弱磁控制部分的成果加以說明無量測器向量控制的部分因為與其它子計畫重疊故從略。弱磁控制的主要目的是減少馬達的激磁以使相同的電源電壓可以驅使馬達轉到較高的速度。但由於激磁的減少，使得馬達參數產生極大的變化，因此弱磁時傳統的向量控制結構無法有效地將激磁與力矩電流的藕合分離，結果使系統的性能降低。本計畫研究皆析弱磁時馬達參數的變化模式，建立實用的弱磁控制架構並設計控制法則，同時研究適合於弱磁控制之電流控制方法，最後透過系統模擬與實驗的方法來驗証設計的控制法則。The objective of field weakening is to reduce field strength of the motor in order to allow the motor to run at higher speed without exceeding the voltage limit imposed by the power supply. When the field is weakened the motor parameters also undergoes significant variations. This will cause detune of the vector control and then lowers the perofrmance of the drive. The project investigated the variation of the motor parameters in the field wekaening operation, construct their control models, and then use the model to design a practical field weakening control schemes. In addition, current regulator suitable for the field weakening control is also investigated.
