本論文探討應用於永磁同步馬達之無位置感測器驅動控制，一般而言，永磁同步馬達需透過編碼器或解角器等位置感測器，回授轉子位置信號以供控制器進行轉速控制。然而轉子位置感測器受外力等因素使其通訊斷線時，馬達將瞬間失去轉子回授信號，其將造成馬達失去控制因而發生失速等安全問題。因此為了在無位置感測器下實現永磁同步馬達速度控制，本論文利用空間向量脈衝寬度調變輸出之脈波電壓，與其電壓作用下之馬達電流，兩者之間的關係計算出馬達反電動勢，並獲得轉子角度位置。然而死區(dead time)效應將使注入之電壓波形失真，因而造成估測之轉子角度位置上的誤差，故本論文透過預測電流的方式，以補償由於失真電壓波形所引起的估測角度誤差。文中利用Simulink電路模擬軟體驗證本論文所提之無位置感測器控制之可行性。

This thesis discusses the position sensorless drive control applied to permanent magnet synchronous motors. Generally permanent magnet synchronous motors need to use position sensors such as encoders or resolvers to feedback rotor position signals for the controller to perform speed control. However, when the rotor position sensor is disconnected due to external forces and other factors, the motor will instantly lose the rotor feedback signal, which will cause the motor to lose control and safety problems such as stalling. Therefore, in order to realize the speed control of a permanent magnet synchronous motor without a position sensor, this thesis uses the space vector pulse width modulation output pulse voltage, the motor current under the action of the voltage, and the relationship between the two to calculate the motor reaction electromotive force and obtain the rotor angular position. However, the dead time effect will distort the injected voltage waveform, which results in an error in the estimated rotor angle position. Therefore, this thesis uses the method of predicting current to compensate for the estimated angle error caused by the distorted voltage waveform. In this thesis, Simulink circuit simulation software and the Hardware-in-the-Loop technology are used to verify the feasibility of the position sensorless control proposed in this paper.
