Abstract

The observer-based static output feedback control problem for discrete-time switched systems is investigated. A sufficient condition of stability for the switched systems under arbitrary switching is obtained by using switched Lyapunov function approach. The linear matrix inequality (LMI) of the condition is parameterized by a scalar variable which allows extra degree of freedom for design problems and stability analysis. Thus, the stability condition has less conservative. Finally, a simulation example is given to illustrate the effectiveness of the result in this paper.
