The present work addresses the stability issue of switched linear systems (SLSs) subject to event-triggered control. We presume that the feedback controller acquires the switching signals and systems state information only at event-triggered sampling instants. An event triggering strategy is presented for both control and switching. Meanwhile, sufficient condition is obtained to stabilize the event-triggered switched linear systems. In addition, we prove that the Zeno behavior can be excluded through the proposed event triggering strategy. Finally, the speed regulation of a turbofan engine model shows that the derived technique is practicable.
本文研究了基于事件触发控制的切换线性系统（SLS）的稳定性问题。我们假定反馈控制器仅在事件触发采样时刻获取切换信号和系统状态信息。针对控制和切换提出了一种事件触发策略。同时，得到了使事件触发切换线性系统稳定的充分条件。此外，我们证明了通过所提出的事件触发策略可以排除芝诺行为。最后，对一个涡轮风扇发动机模型的调速表明所推导的技术是可行的。
