摘要：

In this paper, we study the finite time stability of nonlinear switched systems consisting of both stable and unstable subsystems. First, the finite time stability of systems is studied using the activation time of the subsystems. We show that if the total activation time of unstable subsystems is relatively small compared with that of finite time stable subsystems, then finite time stability of switched systems is guaranteed. Second, the finite time stability of systems is studied based on the comparison principle. We show that if the comparison system is finite time stable, then the finite time stability of switched systems is guaranteed. Finally, a concrete application is provided to demonstrate the effectiveness of the proposed methods.
