강인제어를 위한 출력귀환 제어기법의 비교연구

When mathematical models are used to describe real systems, the differences between the mathematical models and the real systems can cause poor performance of control systems. Therefore, when controllers are used to reduce the random vibration because of external excitation, we cannot expect that control systems achieve satisfactory control result. Hence, it is important that robust feedback stabilization of uncertain systems has been one of main topics in control system are presented using the state-space approach. Also, comparison of discrete-time and unified output feedback control with uncertainty is illustrated. Throughout this study, we will find out which approach is better on the analysis of control system stability with parameter uncertainty.
