碩士 === 和春技術學院 === 電機工程研究所 === 97 === T-S fuzzy model is widely used to represent a nonlinear system in the past few years for the fuzzy control system analysis and design。 The concept of parallel distributed compensation (PDC) is employed to design a fuzzy controller from the T-S fuzzy model。Based on the Lyapunov stability theorem，some stability conditions derived in this thesis。The stability conditions can be reduced to the problem of linear matrix inequity. We use the Matlab LMI Control tool box to solve the controller gain matrices。The provided fuzzy controller will stabilize the unstable T-S fuzzy systems and unstable time-delay systems。Some examples are adopted to demonstrate the feasibility and effectiveness of the proposed control scheme。
