In this article, the event‐triggered (ET) output feedback control problem is discussed for a class of p$$ p $$‐normal nonlinear time‐delay systems. Different from the related existing literature, the linear growth condition is relaxed to the homogeneous one and the growth rate is unknown. In the case of unknown time‐varying delays and control coefficients, nonsmooth control law and some extra redundant terms will be encountered in the design of ET controller, which would bring substantial challenges to the achievement of global convergence. To cope with unknown growth rate and time‐varying delays, two dynamic gains and an appropriate Lyapunov–Krasovskii functional (LKF) are introduced. Then, a new dynamic ET mechanism is given, in which the triggering threshold can be tuned dynamically. It is proved that all the signals of the closed‐loop system (CLS) are bounded. Corresponding examples are given to indicate the validity of the developed theoretical results.

This article investigates the adaptive output feedback control problem for a class of switched stochastic nonlinear systems via an event‐triggered strategy. By virtue of the dynamic gain technique, a novel event‐triggered adaptive output feedback controller is designed. It is proved that all states of the closed‐loop system are globally asymptotically stable in probability. Two examples are presented to verify the effectiveness of the proposed scheme.
