An event-triggered control (ETC) system transmits data packages and updates control inputs only when the predefined criterion is satisfied. In this way, network communication and computing resources are scheduled more reasonably in contrast to the traditional periodic sampling strategy. Small-gain approach proposed in recent literatures is a new modeling method to deal with nonlinear ETC systems. Different from traditional ETC models, stability criteria are proposed in the form of input to state stability (ISS) gain to design the triggering mechanisms. This paper introduces additional dynamic variables in this model and proposes a small-gain based dynamic event-triggered strategy. Sufficient conditions to guarantee the stability of the system are derived with the help of cyclic-small-gain theorem and Zeno behaviors are avoided to ensure the feasibility of this method in practical applications. Numerical simulations are given to demonstrate the effectiveness of our approach.

非线性系统的动态事件触发控制：一种小增益方法

事件触发控制（ETC）系统仅在满足预定义标准时才发送数据包并更新控制输入。这样，与传统的周期性采样策略相比，网络通信和计算资源的调度更加合理。最近文献中提出的小增益方法是一种处理非线性ETC系统的新建模方法。与传统的ETC模型不同，以输入状态稳定性（ISS）增益的形式提出了稳定性标准，以设计触发机制。本文介绍了该模型中的其他动态变量，并提出了一种基于小增益的动态事件触发策略。借助循环小增益定理得出了保证系统稳定性的充分条件，并避免了Zeno行为，以确保该方法在实际应用中的可行性。数值模拟表明了我们方法的有效性。
