Stabilization of Switched Systems Subject to Actuator Saturation by Output Feedback

This paper presents sufficient conditions for asymptotic stabilizability of switched discrete-time linear systems subject to actuator saturations using output feedback. The results are obtained by using a composite Lyapunov function and are given in the form of LMI conditions. It is shown that the union of all the associated level sets is a set of asymptotic stability of the switched system. A numerical example is used to illustrate the technique
