guaranteed cost control robust control delay systems non-fragility distributed delays stochastic stability
By introducing a linear quadratic cost function,the robust guaranteed cost control problem for uncertain stochastic systems with distributed delays and Markovian switching is investigated.Via the application of Lyapunov stability theory and the linear matrix inequality techniques,a delay-dependent sufficient condition is given for the existence of the non-fragile guaranteed cost controllers in the cases of additive perturbation.The controller guarantees the robust stochastic stability of the closed-loop system,and the upper bound of quadratic performance.A numerical example is presented to illustrate the effectiveness of the proposed methods.
