切換式磁阻馬達具有高轉矩、高效率、高功率密度、無轉子繞組以及成本低廉等優點。然而,定、轉子雙凸極式的結構,使馬達磁路高度非線性,導致輸出轉矩漣波大,造成高性能控制器設計不易。因此,本研究以模糊控制理論設計一自調適模糊速度控制器,此控制器擁有即時調適功能,具有克服系統非線性的能力,並透過轉矩分配策略,植入切換式磁阻馬達直接轉矩控制驅動系統中,使系統速度與電磁轉矩動態響應具有高性能的表現。
本研究利用dSPACE-DS1104訊號處理平台來實現本研究的控制策略,驗證出所設計速度控制器之性能及可行性。將自調適模糊速度控制器與轉矩分配函數植入切換式磁阻馬達直接轉矩控制驅動系統中,經由實驗結果證明,在轉速範圍36 rpm至2000 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內,且具有良好的電磁轉矩響應,由此可知此控制策略確實能有效提升系統之動態響應。


This thesis applies fuzzy control theory to design the self-tuning fuzzy controller (STFC) on direct torque control system with torque sharing strategy for switched reluctance motor drive. The merits of SRM include large torque, high efficiency, high power density, no rotor windings and low cost. However, the inevitable high nonlinearities caused by the structure of salient poles of SRM on both rotor and stator lead to great output torque ripple and make SRM difficult to design high performance controller. To overcome these drawbacks, this thesis proposes the STFC that has online tuning ability in order to achieve outstanding tracking performance and torque response.
The proposed scheme was implemented on the dSPACE-DS1104 experimental platform for verifying the feasibility and effectiveness. From simulations and experimental results show that the proposed control method has superior dynamic response in wide speed range (36-2000 rpm).
