| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 93 === The purpose of this thesis is to design and implement a fuzzy sliding-mode controller (FSMC) for the vector-controlled induction motor drive. Constantly switching signal by using sliding mode control can let system approach sliding surface designed. It could reduce disturbance outside or uncertainty by change of system parameters. Nevertheless, the most important drawback is so-called chattering by high frequency. For this reason, we quote the fuzzy logic control, and this idea would smooth the response in permanent state. Moreover, fuzzy logic has the advantages reducing the system complexity and making easy control rule.
Experiments are setup by a PC-Based visual module to inverter to evaluate the effectness of proposed method. The performance of FSMC is compared with the conventional PI controller, sliding-mode controller through the TECO 1-hp induction motor. The experimental results demonstrate that FSMC attains the better performance than others. Also, it verifies the feasibility of our control strategy.
