摘要

This paper is concerned with the asynchronous H-infinity control problem for a class of discrete-time switched systems under dwell time constraint. A state-dependent switching strategy that obeys a dwell time constraint is constructed by using an improved dwell-time dependent Lyapunov function (DTDLF). More incisively, this switching strategy not only makes the considered systems stable with a weighted l(2) -gain, but also allows the value of DTDLF to increase at the switching instant. Dwell-time dependent asynchronous H-infinity controllers are designed by solving a set of linear matrix inequalities. It has been shown that the obtained results also facilitate the studies of stability, l(2)-gain analysis for discrete-time switched systems under zero control input and synchronous switching control, respectively. Finally, three simulation examples are provided to illustrate the effectiveness and potential of the proposed method. (C) 2018 Elsevier Ltd. All rights reserved.
