N2 - In this paper, we consider stability analysis and design for switched systems consisting of linear discretetime descriptor subsystems. When all descriptor subsystems are stable, we show that if the descriptor matrix and all the subsystem matrices are commutative pairwise, then the switched system is stable under arbitrary switching. We also extend the result to the case where all subsystems have different descriptor matrices. Under the same commutation condition, we show that in the case where all the descriptor subsystems are not stable, if there is a stable combination of the unstable descriptor subsystems, then we can establish a class of switching laws which stabilize the switched descriptor system.
