本論文主旨在於研製一套以數位訊號處理器為基礎之交流馬達驅動系統，使用德州儀器(Texas Instruments, TI)公司所製造的數位訊號處理器(digital signal processor, DSP)TMS320F240作為控制晶片。由於數位訊號處理器具有比一般傳統微控制器快約5~10倍的運算能力，所以能實現複雜的控制演算法則，且TMS320F240具有完整的馬達控制介面，可達到以DSP軟體為主之全數位化交流馬達控制。另一方面，使用智慧型功率模組(intelligent power module, IPM)並配合其它控制與保護線路製成反流器(inverter)，完成一套數位控制10KW交流馬達驅動器及控制系統，本驅動系統可對感應或直流無刷馬達做高精密之速度與位置控制。本文應用數位訊號處理器及其介面來執行驅動控制中包含電壓頻率等比例控制、間接磁場導向控制以及伺服控制器。最後，由模擬與實驗結果驗證利用先進的DSP控制技術，可完成高性能交流馬達驅動控制系統。

This thesis presents the development of a digital-signal-processor (DSP) based AC motor drive system, in which the control processor is TMS320F240 DSP produced by Texas Instruments (TI). Since the DSP has excellent computation capability and the computating speed is 5~10 times faster than the conventional microcontrollers, complicated control algorithms can be realized in the DSP. Moreover, owing the complete motor control interfaces of TMS320F240, this DSP can achieve the objective of fully digital AC motor control. Furthermore, intelligent power modules (IPM) and other control and protect circuits are used to implemented a 10KW AC motor drive system. The drive system proposed in this thesis can accomplish high-precision speed and position control for induction motor and DC brushless motor. In this thesis, the DSP and it*s I/O interface are used to implement control algorithms of motor drive system, which comprises the volts/hertz constant control (scalar control), indirect field-oriented control (vector control) and servo controller. Finally, from the simulation and experimental results, the high-performance motor drive system can be achieved using advanced DSP control technique.
