摘要: In this paper, a sojourn-probability-dependent method is proposed to investigate the robust H"~ control for class of switched systems with input delays. The considered system has following characteristics: (1) it consisting set subsystems; (2) sojourn probabilities (i.e. probability staying in each subsystem) are assumed be known (or partly known) prior; and (3) there delays parameter uncertainties subsystem. By using information, new type model built. Lyapunov functional method, mean square stability criteria obtained under two conditions: (A) all subsystems known; (B) only known. Then controller feedback gains derived by cone complement linearization method. An inverted pendulum numerical example given demonstrate effectiveness applicability
