本文旨在分析及製作永磁式同步電動機之轉速和位置控制系統，將同步電動機靜止座標之物理量轉換至旋轉座標系統，化簡永磁式同步電動機之動態模式，以便於分析及模擬，進而進行實體製作。傳統的類比控制方法精度低且不易維修，因此採用數位控制的方法來實現。
本文以德州儀器之定點式數位信號處理器TMS320F240作為控制核心，可利用程式技巧達到浮點運算，其內建之週邊功能非常適合電動機控制，可大幅簡化控制電路、降低成本及增加系統可靠度，因此硬體製作只有電源供應部份、電氣隔離、驅動器及電流回授電路，其餘的部份皆可以軟體程式來完成。

This thesis presents the analysis and implementation of a DSP-Based speed and position control system for permanent-magnet synchronous motors. It first converts the componenet of stationary frame to the synchronously frame. This conversion simplifies the dynamic model of the permanent-magnet synchronous motor for carrying out analysis, simulation, and control system implementation. The control accuracy of the conventional analog control systems is poor and maintainess is not easy. Thus, in this thesis, implementation of the control system is based on a digital signal processor.
A digital control system for a 200W AC permanent-magnet synchronous motor is realized through fixed-point digital signal processor (DSP TMS320F240), and based on the programming skill, the floating-point operation can be implemented easily. Its internal functions are adaptive to the motor control. In addition to those advantages, it can also simplify control circuits, lower the cost, and increase reliability of the systems. The hardware implementation of this control system only includes power supply, driver and current feedback circuit. The rest of parts are realized by the software.
