Design of State Feedback Control with Adjustable Parameter
一类带调节因子的状态反馈控制设计

In this paper,the state feedback control with ad- justable parameter for linear time-delay systems is studied.If the adjustable parameter is reduced,the allowable maximum delay will be extended.When delay is fixed,different feedback gains are gotten by choosing different adjustable parameters, therefore,dynamic performance of closed-loop systems can.be optimized by taking proper adjustable parameters.By design- ing adaptive law of the adjustable parameter,and introducing it into the stability condition of closed-loop systems,the feedback gains which change with time are gotten.Compared with the re- suits by fixed feedback gains,the proposed method in this paper leads to less conservatism,and the better dynamic performance of closed-loop systems is obtained.Simulation example is given to show the effectiveness of the proposed approach.
