直接轉矩控制技術具有不需複雜的座標轉換與解耦合計算及提供快速的轉矩響應等優點，而本論文主要的目的就是實現永磁無刷馬達之直接轉矩控制技術。
利用永磁無刷馬達之直接轉矩控制技術所得之磁通與轉矩誤差，藉此經由開關切換表選擇開關切換狀態以控制變頻器。而速度控制迴圈是由比例積分控制器所組成，並於本論文中探究控制器之設計。
本論文之實驗是利用PC-Based馬達控制系統來確認理論分析並以SimulinkR為發展軟體，實驗結果顯示永磁無刷馬達之直接轉矩控制技術的成果滿足且確實能夠完成上述所提之論點。

It is well known that the features of DTC include not requiring complex coordinate transform and decoupling calculations, and with fast torque response. The objective of this thesis is to implement a Permanent Magnet Synchronous Motor (PMSM) based upon Direct Torque Control.
The implemented DTC-based PMSM motor drives generates the flux and torque errors, and thereby selecting the switching states via switching table for inverter control. The speed control loop consists of a proportional-integral (PI) controller. The details for the controller design are also explored in this thesis.
Experimental results derive d from a PC-based control system are presented to confirm the theoretical analysis and software development, which is developed using Simulink. Experimental results show that the tracking performance of the developed DTC-based PMSM drive is satisfied and confirming the above-mentioned claims.
