摘要:	本論文旨在開發以數位訊號處理器為基礎的無位置感測器永磁同步馬達驅動系統。首先，先利用編碼器(encoder)與簡單的PI控制器建構出馬達電流迴路與速度迴路控制架構。接著加入永磁同步馬達無位置感測器控制技術，本論文是以實現低轉速下無位置感測器控制為主，所採用的方法為初始位置估測法與高頻注入啟動法來代替位置感測器，實現永磁同步馬達無感測器驅動。 ;This thesis is mainly concerned with the development of a DSP- based position sensorless Interior Permanent-magnet synchronous motor (IPMSM) drive. First, a standard IPMSM drive which use a encoder to feedback motor’s position is established, and a simple P-I controller is employed in the standard IPMSM drive to develop the current loop and the speed loop. Next, the position sensorless algorithm of a motor combines with the standard IPMSM drive. In this thesis, the speed of a motor is operated at low speed and also zero speed, so, the algorithms of High Frequency Injection which is suitable in low speed range and Initial rotor position estimation are employed to replace encoder. Finally, a position sensorless IPMSM drive is established.
