摘要
This article investigates time-varying dynamic output feedbackH∞control problem for discretetime switched systems by using a time-varying Lyapunov function.Aswitching rule that depends on available information provided by measured output and time simultaneously is designed for the system with all unstable subsystems.Conditions for l2-gain performance and time-varying controller synthesis are obtained under this switching rule.It provides a more general framework of analyzing discrete-time switched linear systems as it contains the min-switching as special cases when dwell time is not enforced.Finally,an example shows the effectiveness of the proposed method.
