Abstract

This paper focuses on event-triggered consensus control for multi-agent systems subject to undesirable sensor signals. First, a descriptor observer is developed for each agent to estimate the sensor fault and the estimation error can be reduced to be small enough by tuning an nonsingular suppression matrix. Then, leader-follower event-triggered consensus protocol is designed for each agent under directed topology. By virtue of the Jordan form of the Laplacian matrix, the stability conditions are derived using Lyapunov analysis. Zeno behavior can be excluded for all agents. Finally, numerical simulations are conducted to demonstrate the effectiveness of the proposed design.
