This paper investigates the problem of dynamic event-triggered output feedback tracking control for a class of $p$ -normal nonlinear systems with unknown growth rate. To cope with the unknown growth rate imposed on the system nonlinearities, a dynamic gain technique is introduced and a constructive coordinate transformation is given. On the other hand, an event-triggered strategy combining with the dynamic gain is proposed such that the triggering threshold can be adjusted in an adaptive manner. With the help of the proposed event-triggered strategy, a dynamic event-based output feedback controller is developed to ensure that all signals of the closed-loop system are bounded while the tracking error converges to a small neighborhood of the origin. Moreover, it is proved that the Zeno behavior is excluded in the presence of nonsmooth controller. Two examples, including an induction heater circuit system and a numerical example, are provided to indicate the effectiveness of the proposed control method.

一类p-正规非线性系统的动态事件触发跟踪控制

本文研究了一类具有未知增长率的$p$-正态非线性系统的动态事件触发输出反馈跟踪控制问题。为了应对施加在系统非线性上的未知增长率，引入了动态增益技术并给出了建设性坐标变换。另一方面，提出了一种结合动态增益的事件触发策略，可以自适应地调整触发阈值。借助所提出的事件触发策略，开发了一种基于动态事件的输出反馈控制器，以确保闭环系统的所有信号都是有界的，同时跟踪误差收敛到原点的一个小邻域。此外，还证明了在存在非光滑控制器的情况下，Zeno 行为被排除在外。
