Leader-following output consensus of T-S fuzzy switched multi-agent systems under bumpless transfer control and event-triggered communication

Abstract

This paper studies the leader-following output consensus problem of a class of nonlinear switched multi-agent systems described by the T-S fuzzy models. A sufficient condition on the leader-following output consensus and the bumpless transfer performance is developed via co-design of the observer-based bumpless transfer fuzzy controllers and the agent-dependent switching law, which the local stabilizability of all the fuzzy subsystems of each agent is not required. By using the distributed dynamic event-triggered rule, the fuzzy estimator for each agent is constructed to estimate the state of leader. Besides, Zeno behaviour is ruled out via discussing the existence of the lower bound on inter-event intervals. Finally, two examples are given to validate the effectiveness of our results.
