切換式磁阻電動機(Switching Reluctance Motor, SRM)具有結構簡單、成本低及可靠度高等優勢，但由於雙凸結構所產生之非線性電感及轉矩漣波等特性，因此必須有閉迴路控制之驅動系統來提高其運轉效能。然而，閉迴路的響應性能會因不同的控制參數及運轉條件而改變，如何能使操控者輕易地觀察SRM運轉狀態進而調整控制參數是本論文的研究動機。
本論文利用德州儀器公司之DSP 2812 為控制核心發展切換式磁阻電動機驅動平台，應用軟體線上監控SRM 運轉狀態來調整控制參數，達到不同轉速及轉矩下最佳的響應。文中首先介紹切換式磁阻電動機之結構、原理及數學模式之建立，其次介紹開發系統之硬體電路及軟體介面，接著提出速度及電流閉迴路控制策略，並規劃軟體程式流程完成切換式磁阻電動機驅動系統實體製作。最後以實驗結果來驗證本論文所發展SRM 驅動平台之可行性，並提出結論與未來研究之方向。

The Switching Reluctance Motor (SRM) has several advantages, such as simple structure, low cost, and high reliability. However, its double saliency structure with the non-linear inductance could produce torque ripple during the phase commutation. As a result, a close-loop control is introduced to solve the aforementioned problem and consequently improve the operation efficiency. Nevertheless, the performance of the close-loop response could still be influenced by different control parameters and operation conditions. How to conveniently observe the operation status of a SRM and easily tune the control parameters of the motor drive are the main motivations of this research. In order to achieve the best response for various requirements on speed and torque controls, a Texas Instruments developed digital signal processor (DSP 2812) is used to control the drive system. A real-time monitoring software is applied to observe the tuning process of the controller parameters. This thesis will first introduce the structure, physical theory, and the mathematic model of the SRM. The hardware circuit and software interface for the motor drive will be presented in the next section. Following that, test results from the real-time tuning on speed and current mode controls of the SRM will be presented. Finally, we will evaluate the feasibility of the proposed SRM drive system with the concluding remarks and future work.
