Delay-Dependent Stability Analysis of Uncertain Fuzzy Systems with State and Input Delays under Imperfect Premise Matching

Abstract EN

This paper discusses the stability and stabilization problem for uncertain T-S fuzzy systems with time-varying state and input delays.

A new augmented Lyapunov function with an additional triple-integral term and different membership functions of the fuzzy models and fuzzy controllers are introduced to derive the stability criterion, which is less conservative than the existing results.

Moreover, a new flexibility design method is also provided.

Some numerical examples are given to demonstrate the effectiveness and less conservativeness of the proposed method.
