摘要:
借助于事件触发机制,研究了切换奇异系统的有限时间稳定性问题。首先, 引入切换奇 异系统有限时间稳定的概念, 并提出事件触发机制。然后, 在事件触发基础上提出状态反馈控制器。其次, 利用Lyapunov函数和平均驻留时间方法, 得到切换奇异系统稳定的充分条件。最后, 给出数值例子说明结论的有效性。

Abstract:
The finite-time stability problem for switched singular systems based on event-triggered scheme is studied. First, the concept of finite-time stable for switched singular systems is introduced, and event-triggered scheme is proposed. Then, the state feedback controller based on event-triggered is designed. Further, by employing average dwell time technique and Lyapunov function method, the sufficient condition for the finite-time stability of switched systems is obtained. Finally, a numerical example is provided to illustrate the effectiveness of the given conclusion.
