本篇文章主要是討論將一個離散的系統，利用切換式T-S模糊大型系統來做控制。本論文根據局部區段非線性的方法，將一個非線性的大型系統轉換成切換式T-S模糊大型系統，並且在控制器設計方面，設計出以分散式控制為概念的切換式平行分佈補償(parallel distributed compensation, PDC)模糊控制器；接著，再以李亞普諾夫穩定性分析的方式，推導出可使離散切換式T-S模糊大型系統達到收斂且漸近穩定的線性矩陣不等式(linear matrix inequalities, LMIs)條件。最後以兩個例子來說明本論文所推導出來的定理是穩定且有效的控制器設計準則。 This paper discusses a discrete system controller design for switching T-S fuzzy large-scale system. According to the local sector nonlinearity method, a nonlinear large-scale system can be represented as a switching T-S fuzzy large-scale system. Then the switching decentralized parallel distributed compensation (PDC) fuzzy controller is synthesized. Base on Lyapunov stabilization criterion, the linear matrix inequalities (LMIs) conditions are derived, for ensuring the stability of the switching T-S fuzzy large-scale system. Finally, we give two examples to illustrate the effectiveness of the proposed criterion.
