摘要

切換式磁阻馬達具結構簡單、成本低、散熱佳與效率高等優點，其結合感應馬達、直流馬達和直流無刷馬達的特點，極適合應用於可調速驅動系統。為了使馬達在系統參數變動及負載干擾情形下，得到較佳速度響應及負載干擾消除能力，本文提出積分比例控制結合反終結(anti-windup)控制策略作切換式磁阻馬達速度控制，即當控制器輸出飽和時，便前饋一個量到控制輸入端以抑制飽和現象，藉以降低系統響應超越量及減少上升時間，使驅動系統得到較佳暫態響應及負載干擾之消除。最後以現場可程式邏輯閘陣列(FPGA)為基礎建構一全數位化變速驅動系統，並透過個人電腦建立即時人機控制系統，驗證本控制法則的正確性及可行性。

A switched reluctance motor has the advantages of simple structure, low manufacturing cost, cool easily and high efficiency. It combines many desirable qualities of induction motor drives, DC motor drives, and PM brushless DC systems. To achieve good dynamic performance, an IP structure controller with anti-windup is employed to reduce the effects of motor and mechanical parameter variations and provide a good disturbance rejection. If the IP controller output is saturated, the integral state is reset to zero with a rate of the integral time constant by negatively feeding back the controller output. In the proposed method, both the overshoot and the rise time in tracking can be reduced. All the designed SR motor controllers are implemented by using a FPGA and personal computer to establish an online user interface, and the robustness of tracking performance is verified when subjected to parameter uncertainties and load disturbance.
