The problem of event-triggered control for a class of uncertain nonlinear systems subject to p-norm is investigated in this paper. Note that the input-to-state stability (ISS) assumption related to the measurement error and the assumption on the existence of a stable controller are removed in this paper. With the help of adding a power integrator technique, intermediately control signals are presented to address the uncertainties and nonlinearities of the system under a fixed/relative threshold strategy, which plays an important role in the design of the event-triggered controllers. A rigorous Lyapunov stability analysis method is put forward to verify that all the signals of the closed-loop system are globally uniformly bounded and converge to an arbitrarily small set. Finally, an application of an underactuated mechanical system demonstrates the effectiveness of the designed scheme.

服从p的一类不确定非线性系统的事件触发控制问题-范数在本文中进行了研究。注意，本文删除了与测量误差有关的输入到状态稳定性（ISS）假设和关于存在稳定控制器的假设。借助于添加功率积分器技术，提出了中间控制信号，以解决固定/相对阈值策略下系统的不确定性和非线性，这在事件触发控制器的设计中起着重要作用。提出了一种严格的Lyapunov稳定性分析方法，以验证闭环系统的所有信号在全局上是均匀有界的，并且收敛到任意小的集合。最后，欠驱动机械系统的应用证明了所设计方案的有效性。
