碩士 === 中原大學 === 電機工程研究所 === 99 === This thesis focuses on the maximum power tracking for permanent magnetic synchronous generating (PMSG) based wind power energy conversion system (WECS). To achieve the control objective, a DC/DC buck converter is used as the power regulation circuit. Then, the T-S fuzzy tracking controller is designed to drive the operating system to the maximum power point. In the controller design process, the nonlinear model is initially represented into a T-S fuzzy form such that both controller and observer can be obtained via Lyapunov stability analysis and Matlab LMI toolbox. Both simulations and experiments are established to verify the controller’s performances. Moreover, a PI controller is used in comparisons with the proposed controller. In the experiment environments, a real time DSP card dSPACE DS1103 digital processor is used to realize the proposed controller. Finally, the results show good performances in robustness and maximum power tracking for the proposed approach.
