This paper studies the interval observer-based event-triggered controller design for switched systems involving additive disturbance and measurement noise. We first extend the definition of asymptotic interval observers for general non-switched systems into switched ones. Then, by giving the bound of the disturbance and the measurement noise and adopting the multiple Lyapunov function method, some sufficient conditions are derived and applied to build the interval observer, which supply certain information at any instant: an upper bound and a lower bound are provided for each component of the states. Next, we propose an event-triggered sampling mechanism and design an interval observer-based state feedback controller for the considered switched systems. Finally, we afford two examples to illustrate the validity of the derived results.

本文研究了基于时间间隔观测器的事件触发控制器设计，该系统涉及包含附加扰动和测量噪声的开关系统。我们首先将一般非交换系统的渐近间隔观测器的定义扩展为交换系统。然后，通过给出干扰和测量噪声的界限，并采用多重李雅普诺夫函数方法，推导了一些充分的条件，并将其应用于构建间隔观测器，该观测器可以随时提供某些信息：上限和下限是提供给州的每个组成部分。接下来，我们提出一种事件触发的采样机制，并为所考虑的开关系统设计基于间隔观察器的状态反馈控制器。最后，我们提供两个示例来说明得出的结果的有效性。
