| Abstract: | The problem of LQ suboptimal control with static output feedback control for uncertain continuous systems is investigated. Base on the output feedback, a sufficient condition for the problem is given in terms of linear matrix inequalities （LMIs） .The output-feedback is designed. The closed-loop systems are guaranteed to be stable. Numerical example is given to show the effectiveness of the proposed method. |
