摘要

本研究利用一種直接轉矩控制概念，應用於切換式磁阻馬達驅動系統中，所使用的直接轉矩控制架構能使系統動態響應更加快速且具有高性能的表現。切換式磁阻馬達具有效率高、高轉矩、成本低廉等優點。然而，馬達本身磁路高度非線性的特性，導致輸出電磁轉矩漣波大、運轉聲音大、控制器設計不易等問題。因此，本研究設計所應用的直接轉矩控制架構，並以模糊理論設計一速度控制器，植入所應用之控制架構中加以改善系統動態響應性能。
本研究利用dSPACE-DS1104訊號處理平台來實現所應用的控制策略，驗證出所使用的直接轉矩控制系統之模糊速度控制器設計之性能及可行性。經由實驗結果證明，在轉速範圍100 rpm到2000 rpm，負載轉矩1 Nm，轉速於穩態時皆能維持在 2 rpm以內，並且能具有快速良好的電磁轉矩響應。由此可知所應用之控制架構確實有效提升系統之動態響應。

In this thesis, a direct torque control strategy is proposed , which is practical and applicable for the switched reluctance motors (SRMs) drive system. The proposed direct torque control system achieves outstanding performance in dynamic response. The merits of SRMs include high power density, high efficiency, large torque and low cost. However, the inevitable high nonlinearities caused by the structure of salient poles of SRM on both rotor and stator lead to large output torque ripple and acoustic noise,and make SRM difficult to control. Therefore, the direct torque control strategy is proposed, and a fuzzy speed controller is designed to improve the switched reluctance motor performance in speed response.
The proposed scheme was implemented on the dSPACE-DS1104 experimental platform for verifying the feasibility and effectiveness. As shown in the experimental results, the SRM drive system achieves satisfactory performance in wide speed range (100-2000 rpm), and the proposed control strategy has superior dynamic response.
