本文旨在改善模糊控制器於速度穩態時的缺點，模糊控制器控制效果取決於模糊規則庫以及模糊歸屬函數選取，模糊規則庫及模糊歸屬函數的多寡也會影響模糊控制精度，於穩態時，輸出轉速會有一些誤差差存在。針對此問題，本文提出積分模糊控制器改良穩態誤差，藉由決策器與積分模糊控制器之結合以降低系統響應之超越量，並以PSIM軟體加以模擬。最後提出永磁同步馬達速度迴路控制之實驗結果以驗證本研究之有效性。 The article mainly aims to improve fuzzy controller’s defect in steady state. The performance of the systems depends on the selection of the fuzzy rules and fuzzy membership functions. The number of Fuzzy rule and fuzzy membership function will also influence the accuracy of fuzzy control. In steady state, there are some errors. The article proposes to use integral-fuzzy controller to improve the steady state errors. The integral fuzzy controller is added, combined with the decider to reduce the overshoot of the system response. Furthermore, using PSIM software to simulate fuzzy controller, integral-fuzzy controller and integral-fuzzy controller with decider. Finally the experimental results and discussions are shown to verify the effectiveness of the present work.
