An H∞ Output Feedback Control for Uncertain Singularly Perturbed T-S Fuzzy Systems

다국어 초록 (Multilingual Abstract)

This paper deals with an H∞ output feedback controller design for uncertain singularly perturbed T-S fuzzy systems. Integral quadratic constraints are used to describe various kinds of uncertainties of the plant. It is shown that the H∞ norm of the uncertain singularly perturbed fuzzy system is less than γ for a sufficiently small ε>0 if the H∞ norms of both the slow and fast subsystem are less than γ. Using this fact, we develop a linear matrix inequality based design method which is independent of the singular perturbation parameter ε. A numerical example is provided to demonstrate the efficacy of the proposed design method.
