Abstract

This paper extends the event-triggered communication in consensus problems of multi-agent systems to the case of distributed continuous-time convex optimization over weight-balanced digraphs. We address problems whose global objective functions are a sum of local functions associated to each agent. We utilize the event-triggered communication technique to reduce the communication load and avoid Zeno behavior meanwhile. Based on Lyapunov approach, we prove that the Zero-Gradient-Sum (ZGS) algorithm combined with the event-triggered communication makes all agents’ states converge to the optimal solution of the global objective function exponentially fast.
