Takagi-Sugeno Bilinear Based Model Non-fragile Guaranteed Cost Fuzzy Controller Design

In this paper, non-fragile characteristics existing in control systems are studied, and the existing sufficient condition for the non-fragile guaranteed cost control rate based on Lyapunov stable theory are derived, which can ensure the close-loop system asymptotically stability for any allowed uncertainties, and that performance index of the close-loop system doesn’t exceed some upper bound for a given performance function with quadratic form. And we also proposed the designing method for a novel non-fragile guaranteed cost fuzzy controller design for continuous timedelay fuzzy system based on Takagi-Sugeno bilinear model. In the last part, two simulation examples proved the effectiveness of this novel proposed method.
