Output feedback stabilization for a class of switching systems

An observer is designed for a class of switching systems whose sub-systems are linear. A sufficient condition for the stabilization of the system by dynamics output feedback controller is also presented. Based on designing the observer, a switching strategy and sub-controller, which use the observer value, are designed to guarantee that the closed-loop system is exponentially asymptotically stable. When the switching interval time is constrained the switching strategy and sub-controllers can also design to guarantee that the closed-loop system is exponentially asymptotically stable. Finally, an example is given to show the feasibility of the given strategies.
