A Robust Output Feedback Controller Design for Uncertain Linear Systems Using LQG/LTR

LQG/LTR 기법을 이용한 불확실한 선형 시스템의 견실한 출력 되먹임 제어기의 설계

In this paper, a controller design method for uncertain linear systems by output feedback is proposed. This method utilizes the LQG/LTR procedure for systems with uncertainties described in the time domain. It is assumed that the uncertainties satisfy the matching conditions and their bounds are known. First, a robust state feedback controller design method is introduced. Then, it is asymtotically recovered for the output feedback system by the loop transfer recovery(LTR) method under a certain condition.
