Abstract:

The nonfragile robust exponentially stabilization problem for stochastic delayvarying systems with polytopictype uncertainties is discussed，and the perturbed matrix in the actual implemented controller is assumed satisfying polytopictype uncertainties. Based on parameterdependent LyapunovKrasovskii functional and freeweighting matrix method, 〖JP2〗the Lyapunov matrix and systems matrix are separated. Some delaydependent nonfragile stabilization conditions are presented in terms of linear matrix inequalities. 〖JP〗The simulation example shows that the result is efficient.
