本論文提出基於Windows CE.NET環境之感應馬達速度控制系統之研製，首先，根據間接磁通導向控制法，然後使用PI控制法則、滑動模式控制法則、模糊控制法則，重覆控制法則等控制法則，設計各種速度控制器，並利用類比/數位轉換器及數位/類比轉換器作為訊號傳輸介面，以控制感應馬達之轉速。最後，在個人電腦為控制主體之架構下，以微軟公司
提供的EVC(Embedded Visual C/C++)和PB(Platform Builder)開發工具發展驅動程式及控制程式，並應用在Windows CE.NET作業系統中。
經由實驗結果顯示，雖然PI控制器設計簡單，但易受到雜訊干擾而產生穩態誤差；滑動模式控制器可以強化系統的穩定條件進而消除穩態誤差，但易受到雜訊的干擾而產生顫震的現象；模糊控制器則基於適應和非線性的控制而不易受到雜訊干擾，且能比滑動模式控制器及PI控制器有較短的安定時間。
重覆控制器能改善在原控制系統上的週期性干擾，重覆控制器與PI控制器的組合能強化原PI控制器的穩定度；重覆控制器與滑動模式控制器的組合能降低週期性雜訊的干擾而減少顫震的現象；重覆控制器與模糊控制器的組合能加強抗週期性雜訊的性能。

An induction motor speed control system in Windows CE.NET environment is developed in this paper. First, decoupling of the motor torque and rotor flux amplitude is based on the indirect vector control method. Then, PI controller, sliding mode controller, fuzzy controller, and repetitive controller are designed to control the speed of the induction motor. Finally, on the base of PC control structure, we use EVC( Embedded Visual C/C++) and PB(Platform Builder) tool that Microsoft provided to develop driver and control program on Windows CE.NET operation system .
Experimental results show that PI controller is designed easily, but it is sensitive to disturbance, which produce the steady-state error. Sliding mode control can strengthen the steady-sate condition, but it is sensitive to the disturbance, which produce the dither. Fuzzy control is basically an adaptive and nonlinear control, which is insensitive to the disturbance, and the settling time of fuzzy controller is shorter than that of PI controller and sliding mode controller.
Repetitive controller can track periodic reference commands and attenuate periodic disturbances of the control system. The combinations of repetitive controller and PI controller can improve the stability of PI controller. The combinations of repetitive controller and sliding mode controller can reduce the periodic disturbance, and decrease the dither. The combinations of repetitive controller and fuzzy controller can improve the capability of periodic disturbance rejection.
