Three cases of such systems which are composed respectively of a pair of unstable subsystems of both stable and unstable subsystems and of a pair of stable systems are considered. For the first case the proposed result shows that there exists periodically switching rule guaranteeing the exponential stability of the whole system with sufficient small switching period if there is a Hurwitz linear convex combination of two uncertain linear systems derived from two subsystems by certain linearization. For the second case we present two general switching criteria by means of multiple and single Lyapunov function respectively. We also investigate the stability issue of the third case and the switching criteria of exponential stability are proposed. The present results for the second case are further applied to the periodically intermittent control. Several numerical examples are also given to show the effectiveness of theoretical results.
