碩士 === 國立臺灣科技大學 === 自動化及控制研究所 === 97 === This study aimed to design an AC servo motor real-time control system based on personal computer, and develop the permanent magnet synchronous motor (PMSM) drive system by the field-oriented control theory for AC machines. It mainly used software module tools such as MATLAB/Simulink and Real-Time Workshop to integrate system design and establish an experimental advance platform with rapid controller prototyping. The design, simulation and implementation of controller can be carried out on this platform. In the controller design, the rapid achievement of the desire values for the dynamic response of the system and eliminate steady-state errors were the objective of this study. First, this study derived the mathematical model of PMSM, and conducted the traditional compensation design through the pole placement method by using proportional and integral (PI) controller in the current and speed feedback control loop. In addition, this study explored and discussed that the PI controller parameters can be obtained through the Ziegler-Nichols tuning rule of the entire controlled system, and the speed controller adopts optimal PI control using genetic algorithm if the mathematical model of the PMSM is not applied. Next, with current and speed as the state variables, the state feedback would be applied to design the control system. Finally, the design method of using fuzzy logic controller would be employed to make the control system more efficient and produce fast and stable effects as well. The experimental results demonstrated that the established PMSM real-time system have consistent response in motion control simulation and implementation. The proposed controller design method has good properties while its output response has robustness with external loads of disturbance by implementation verification system.
