本論文提出對永磁同步馬達無感測器驅動設計與實現，以馬達反電動勢為基礎，建立估測演算法取代位置感測器，以提供馬達轉子位置與轉速訊息。 以DSP數位訊號處理器為數位永磁同步馬達驅動系統之建立與操控性能之改善研究，編碼器在高電壓高轉速下容易受到電磁波，建立無編碼器回授之估測器，達到穩定輸出與轉速。 本論文以TMS320F28335數位訊號控制器為整個系統核心，與驅動功率模組實現無感測器永磁同步馬達驅動系統。 ;This thesis presents a sensorless control strategy for a surface permanent magnet synchronous motor (SPMSM). Back electromotive force (EMF) in the rotating reference frame is used to estimate rotor position and speed without using encoder since the encoder signal is easily influenced by electrical noise in the high voltage and high motor speed control. Based on TMS320F28335 (DSP), this thesis has successfully established an estimator to replace the encoder and achieved stabilize output rotating speed with the constructed sensorless motor control scheme.
