摘      要：This paper addresses the problem of observer-based gain-scheduled H control for a class of linear parameter-varying systems with time-varying delay in the state.A new delay-dependent and parameter-dependent H performance criterion is developed with a parameter-dependent Lyapunov *** conditions are presented to design gain-scheduled controllers and state observers to guarantee that the resulting closed-loop system is asymptotically stable with a prescribed H performance level in terms of parameterized linear matrix inequalities.A numerical example is given to show the effectiveness of the proposed techniques.
