Abstract :
This study proposes absolute stability conditions and an approximate range of robust stability for a continuous-time T-S fuzzy system. In this paper, the mixed transfer functions to synthesize a T-S fuzzy model in any mixed weighting cases for the stability are introduced. A well-known Extreme Value Theorem and Kharitonov´s Theorem are developed to analyze the stability robustness and to judge the stability conditions. Finally, two numerical examples are given to show the efficiency and the convenience of the method.
