【Abstract】 The guarantee performance control of polytopic uncertain discrete systems was discussed in detail.Based on parameter-dependent Lyapunov stability concept,a sufficient condition for the existence of guarantee cost controller and the techniques of designing the controller of the polytopic uncertain systems were presented.Both the condition and the technique can be completely verified through the feasibility by solving some set of LMIs described at the vertices of the uncertainty domain.The numerical simulation examples are provided to verify the effectiveness of the proposed techniques.更多还原
