Abstract

AbstractThe leader-follower consensus problem of second-order multi-agent systems with uncertainty and directed topology is studied. The event-triggered mechanism is introduced to reduce the communication frequency between the agents. By using sliding mode control, the influence of external disturbance can be released. Self-adaptive method is used to estimate target unknown object. A sliding mode controller based on event-triggered mechanism is presented. The stability of the systems is analyzed by constructing the Lyapunov-Krasovskii function and the Zeno behavior can be avoided. Finally, a numerical example is given to demonstrate the validity of the proposed method.KeywordsMulti-agent systemsEvent-triggered mechanismSliding mode controlSelf-adaptive method
