Design of Self-organizing Fuzzy Controller for Switched Reluctance Motor Direct Torque Control Drive System
摘要
切換式磁阻馬達具有簡單構造、堅固耐用以及成本低廉等優點。然而，由於馬達定、轉子為凸極式結構，導致輸出轉矩具有高度非線性特性，造成控制器設計不易。因此，本研究以模糊控制理論設計一自組織式模糊控制器，具有即時調適模糊規則達到克服系統非線性的能力，應用於切換式磁阻馬達直接轉矩控制驅動系統，使馬達轉速與轉矩具有高性能的響應。 本研究利用dSPACE-DS1104訊號處理平臺來實現本研究的控制策略，經由實驗結果證明，在轉速範圍100 rpm~1600 rpm，馬達負載轉矩為1 Nm，轉速誤差於穩態時皆能維持在 2 rpm以內，可驗證出所設計速度控制器之性能及可行性，在切換式磁阻馬達直接轉矩控制驅動系統中，確實能有效提升系統之動態響應。

The switched reluctance motor (SRM) consists of a simple structure and is rugged, durable, and inexpensive. However, the structure of stator and rotor are salient poles, it leading to a high nonlinear characteristic when rotation torque is output. Consequently, making it difficult when designing the controller. Thus, this study involved applying fuzzy control theory to design a self-organizing fuzzy controller (SOFC). The proposed SOFC controller enables adjusting fuzzy rules to overcome the nonlinear characteristic of the SRM drive system. The SOFC apply SRM for a direct torque control drive system to ensure that the motor provides a high performance of rotation speed and rapid torque response. A dSPACE-DS1104 signal platform is used to manage the control strategy. The results of experiments reveal that, when the rotation speed is within the range of 100 rpm to 1600 rpm, and the motor loading torque is 1 Nm, the speed error in steady state is less than 2 rpm. Therefore, the SOFC can improve the dynamic response of the SRM drive system with direct torque control.
