A study on the design of robust controllers with guaranteed cost bounds

강인 성능을 보장하는 제어기 설계에 관한 연구

In this paper, robust controllers which guarantee the stability and the quadratic performance in the presence of the state and the input matrix uncertainties are presented. Modified quadratic performance indices which include the model uncertainties are proposed for continuous and discrete time linear systems. And it is shown that the solution of the proposed optimal performance problem is the robust controller.
