Robust H∞ control for fuzzy singularly perturbed systems with disturbance time-varying delays

In this paper, a class of uncertain fuzzy singularly perturbed model with disturbance time-varying delays is designed based on the Takagi-Sugeno form. The basic ε-dependent stability conditions are given. Then the H
_∞
γ sub-optimal state feedback control law is investigated in the form of ε-independent linear matrix inequalities. Finally numerical examples are given to show the effectiveness of the proposed method.
