Abstract
En 中文
This article addresses the event-triggered consensus control problem for nonlinear multiagent systems under resource constraints, where a unified event-triggered mechanism (ETM) is proposed to conserve system resources through discrete updates of both control laws and neural networks (NNs). First, an improved dual-level game approach is developed specifically for ETM design, treating the control law and event-triggered error as adversarial players to derive an optimal control law and a maximum allowable triggering error threshold. Unlike existing dual-level game-based ETMs, whose parameter design relies on an unknowable constant bounding the cost function gradient norm with respect to the consensus error, the proposed improved approach eliminates this dependence. Second, within the adaptive dynamic programming framework, event-triggered NNs reduce computational load by updating weights solely at triggering instants with rigorous theoretical guarantees establishing the quantitative relationship between weight estimation errors and cost functions. Finally, the unified ETM coordinates control execution and NN updates via logical “union” relations, ruling out both Zeno and singular phenomena. Simulations validate its effectiveness and superiority.
