 Disturbance observer-based event-triggered impulsive control for nonlinear systems with unknown external disturbancesYing Xing, Xinyi He and Xiaodi Li Mathematics and Computers in Simulation (MATCOM), 2025, vol. 227, issue C, 263-271 Abstract: Input-to-state practical stability (ISpS) of a kind of nonlinear systems suffering from unknown exogenous disturbances is explored in this article, where a disturbance observer is established to estimate the information of the exogenous disturbances. To achieve ISpS of the system, the impulsive controller as well as state-feedback controller are both considered to regulate the discrete and continuous dynamics of the system, respectively. Especially, a novel disturbance observer-based event-triggered mechanism is devised to decide the release of impulsive control signal. Furthermore, several adequate conditions are given for excluding the occurrence of Zeno phenomenon. To confirm the feasibility of the proposed results, two numerical instances and their corresponding simulation results are presented.
