在这篇文章中,我们研究了脉冲系统的Lyapunov稳定性问题,通过事件触发脉冲控制,动力系统的发展根据连续时间方程的大部分时间,但偶尔会出现瞬时跳跃时,脉冲事件被触发。我们给出了基于Lyapunov的一致稳定性和全局渐近稳定性的充分条件。与一般的时间触发脉冲控制不同,事件触发脉冲控制只有在事件发生时才被触发。因此,我们的稳定性条件在很大程度上依赖于事件触发机制的李雅普诺夫函数。此外,芝诺行为可以排除在我们的结果。然后,我们将理论结果应用到非线性脉冲控制系统中,设计事件触发脉冲控制策略来实现所处理系统的稳定性。最后,通过两个数值例子和仿真验证了所提结果的有效性。
In this article, we investigate the Lyapunov stability problem for impulsive systems via event-triggered impulsive control, where dynamical systems evolve according to continuous-time equations most of the time, but occasionally exhibit instantaneous jumps when impulsive events are triggered. We provide some Lyapunov-based sufficient conditions for uniform stability and globally asymptotical stability. Unlike normal time-triggered impulsive control, event-triggered impulsive control is triggered only when an event occurs. Thus our stability conditions rely greatly on the event-triggering mechanism given in terms of Lyapunov functions. Moreover, the Zeno behavior can be excluded in our results. Then, we apply the theoretical results to the nonlinear impulsive control system, where event-triggered impulsive control strategies are designed to achieve stability of the addressed system. Finally, two numerical examples and their simulations are provided to demonstrate the effectiveness of the proposed results.
