Stabilization of a class of discrete-time switched systems via observer-based output feedback

【摘要】：In this paper, observer-based static output feedback control problem for discrete-time uncertain switched systems is investigated under an arbitrary switching rule. The main method used in this note is combining switched Lya- punov function (SLF) method with Finsler’s Lemma. Based on linear matrix inequality (LMI) a less conservative stability condition is established and this condition allows extra degree of freedom for stability analysis. Finally, a simulation exam- ple is given to illustrate the efficiency of the result.
