عنوان فارسی ROBUST $H_{infty}$ CONTROL FOR T–S TIME-VARYING DELAY SYSTEMS WITH NORM BOUNDED UNCERTAINTY BASED ON LMI APPROACH
چکیده فارسی مقاله In this paper we consider the problem of delay-dependent robust
H1 control for uncertain fuzzy systems with time-varying delay. The Takagi–
Sugeno (T–S) fuzzy model is used to describe such systems. Time-delay is
assumed to have lower and upper bounds. Based on the Lyapunov-Krasovskii
functional method, a sufficient condition for the existence of a robust H1
controller is obtained. The fuzzy state feedback gains are derived by solving
pertinent LMIs. The proposed method can avoid restrictions on the derivative
of the time-varying delay assumed in previous works. The effectiveness of our
method is demonstrated by a numerical example.
