Abstract

Abstract: This paper focuses on the problem of observer design for a class of linear switched systems. By constructing appropriate Lyapunov functions and using matrix inequalities, conditions of the exponential convergence of the estimated state observer are obtained. Furthermore, by using state jump at certain time when the change of value of the switched law occurs and specifying the value of the state jump, the system performance is improved. It is shown that the convergence rate of the estimation error can be reduced significantly. Simulation results are given to show validity of the state observer.

Key words: switched systems, unknown switched law, exponential stability, state observer
