LMI optimization approach on robustness and H∞ control analysis for observer-based control of uncertain systems

This paper investigates the observer-based controls for a class of dynamic linear systems with structural parameter uncertainties. Two issues are mainly concerned with LMI optimization techniques: the first regards the robustness analysis of the observer-based control systems without disturbance inputs and the other is the H∞ control when involving disturbance inputs. A numerical example is given to illustrate the main contribution of this paper.
