| Summary: | 碩士 === 國立高雄第一科技大學 === 系統資訊與控制研究所 === 101 === In this study, the proposed hybrid H∞/H2 multi-object T-S fuzzy controller design method on DC-DC Buck converter controller to guaranteed control performance. The common T-S fuzzy controller considers about single object performance which is the H∞ robust immunity, but ignored other important factors which influence controller distinctly such as H2. T-S fuzzy model system has well performance to deal with nonlinear system recently. The proposed method applied T-S fuzzy model system and NSGA II. In order to turn the complex quadratic finite-time integral function into algebra formulation of H2 to find the controller performance indexes. The study used LMI stability constraint techniques and OFA (orthogonal function approach) respectively. NSGA II was applied to search the best solution set of H∞/H2 to make sure the controller with the quadratic finite-time integral performance index and robustness.
