Observer-based output feedback control design for mismatched uncertain systems

Abstract

In this paper, the observer-based output feedback control is developed for a class of mismatched uncertain systems with both mismatched in the state matrix and in the input matrix. The objective is to reduce the conservatism and enhance the robustness of the control systems by using only the estimation error of output variables. The control and observer gains are given from linear matrix inequalities feasible solution. A numerical example is used to demonstrate the efficacy of the proposed method.
