Abstract

This paper investigates the globally uniformly exponential stability of positive switched linear system (PSLS) in both continuous-time and discrete-time contexts. By using the multiple piecewise-continuous linear copositive Lyapunov function (MPLCLF) and exploring mode-dependent average dwell time (MDADT) switching, several stability criteria are developed with a switching strategy where slow switching and fast switching are applied to stable and unstable subsystems respectively. The proposed methods are also used to stabilize PSLS with controllable and uncontrolled subsystems. The obtained results provide lower bounds on MDADT of stable subsystems and higher bounds on MDADT of unstable subsystems and reduce the conservatism compared with the existing results. Finally, two numerical examples are provided to validate the advantages of the obtained results.
