快速終端滑模控制應用於風力發電系統 最大功率點追蹤
Fast Terminal Sliding Mode Control for Maximum Power Point Tracking of Wind Power systems
摘要
本論文之目的在於架構風力發電最大功率點追蹤控制系統，使風力發電能具有最大的輸出效能。本文將採用直流/直流升壓型電力轉換器(DC-DC Boost Power Converter)做為功率調節電路，依據風力發電機特性，設計快速終端滑模控制器(Fast terminal sliding mode controller, FTSMC)進行最大功率點電壓追蹤。其優點為可以提供有限的系統追蹤收斂時間，並可減少滑模函數所產生的顫動現象。為了驗證所提控制方法的有效性，首先以數值模擬其快速終端滑動控制器於風力發電系統之最大功率點追蹤性能，並與PI控制器做比較。在實驗方面，利用風力發電機模擬平台與升壓型電力轉換器進行實驗，並使用dSPACE DS1103數位訊號處理器建構控制器來進行最大功率點追蹤驗證。

The purpose of this thesis is to implement the maximum power point controller for wind energy conversion system(WECS), so that the output of the wind power energy conversion system has the highest efficiency. The thesis uses a DC/DC boost power converter (DC/DC Boost Power Converter) as the power regulation circuit. According to the characteristics of the wind power generator, I design a fast terminal sliding mode controller (FTSMC) for tracking the maximum power point voltage reference. The advantages of the proposed method are in finite convergent time of tracking error and zero steady-state error. To verify the validity of the proposed MPPT method, I carry out FTSMC simulations for the maximum power tracking of the WECS with comparison of PI controller. In the experimental environments, a real-time DSP card dSPACE DS1103 is used to realize the MPPT controller in WECS emulator platform and DC/DC boost power converter.
