This paper addresses the annular finite-time boundedness $H_{\infty }$ control problem for a class of switched fuzzy systems. A novel switching dynamic event-triggered mechanism is proposed to save communication resources; where two different internal variables are designed and change according to a switching manifold. It is proved that the proposed switching dynamic event-triggered mechanism has a larger minimal inter-execution time in comparison with the static one. With a Lyapunov-like function including the internal dynamic variable, a criterion is established to ensure the annular finite-time boundedness $H_{\infty }$ performance. A dynamic event-triggered controller and a set of feasible mode-dependent average dwell time switching signals are co-designed to achieve desired performance. Finally, an example is presented to validate the effectiveness of the proposed method.

本文探讨了环形有限时间有界性 $H_{\infty }$一类切换模糊系统的控制问题。提出了一种新颖的切换动态事件触发机制，以节省通信资源。其中设计了两个不同的内部变量，并根据切换歧管进行更改。实践证明，所提出的切换式动态事件触发机制与静态机制相比具有更大的最小互执行时间。利用包含内部动态变量的类Lyapunov函数，建立了确保环形有限时间有界性的准则$H_{\infty }$表现。共同设计了一个动态事件触发控制器和一组可行的依赖于模式的平均停留时间切换信号，以实现所需的性能。最后，通过一个例子验证了所提方法的有效性。
