Abstract
In this paper, the stability analysis problem is considered for switched linear stochastic systems, where both stable and unstable subsystems are involved, by using the Lyapunov-like function approach. When there is a common Lyapunov-like function for all subsystems, it is shown that the switched system is globally asymptotically stable in probability (GAS-P) if the total activation time ratio of unstable subsystems to stable ones is less than a specified constant. When there is not a common Lyapunov-like function for all subsystems, the proposal is made to use the multiple Lyapunov-like function and to show that in addition to the total activation time ratio requirement, if the average dwell time is sufficiently large, then the switched stochastic system is GAS-P.
