【Abstract】 The robust H-infinity control problem for uncertain stochastic neutral systems with multiple time delays is in- vestigated in this paper.The parameter uncertainties in the systems are assumed to satisfy the generalized matching con- ditions,while the time delays exist in state,control,measure output,exogenous disturbance input and derivative state simultaneously.Firstly,stochastic robust stabilizable criterion is developed via Ito differential rule based on stochastic Lyapunov stability theory.A sufficient condition is then derived for the existence of robust H-infinity control law.All the results are expressed in terms of linear matrix inequality.Finally,a numerical example is given to show that the results are valid.更多还原
