本論文介紹了磁通鏈估測法和偵測電流峰值這兩種無感測式切換式磁阻馬達的控制方法，並經由模擬和實作來驗證這兩種方法。為了驗證這兩種無感測式控制方法的可行性，首先必須先建立馬達的模型，將設計好的馬達參數建表在Simulink上。建立好模型後，就可以藉由模擬來確認演算法的正確性。實作的部分，首先必須先量實際的馬達參數，最後將演算法在切換式磁阻馬達上實現。模擬和實作結果驗證了此兩種控制策略的可行性。

The purpose of this thesis is to simulate and implement a sensorless control system for a switched reluctance motor (SRM). There are two sensorless control methods considered in this study. One is the flux estimation method; the other is the phase current peak detection. To make sure the sensorless control methods are feasible, several issues should be addressed. To begin with, the model of SRM should be built in Simulink. Then, we simulate the sensorless control algorithms in Simulink. The parameters of SRM are measured in experiments. Finally, the sensorless control algorithms are applied to the SRM system. Simulations and implementation verify the feasibility of sensorless control strategy.
