Event-triggered leader-following consensus control of nonlinear multiagent systems with generally uncertain Markovian switching topologies

This article focuses on the event-triggered consensus control (ETCC) issue of the time-varying delayed leader-following nonlinear multiagent systems (TVDLFNMASs). In order to minimize the influence on uncertain factors of the information transmission and the data information loss, the switching topologies are constructed as the generally uncertain Markovian jumping forms whose transition rates include completely unknown elements and estimate values of uncertain elements. In addition, the event-triggered (ET) transmission strategy is given based on the threshold parameter and the ET matrix to relieve the communication burden of TVDLFNMASs. The new leader-following (LF) consensus conditions and control gains are obtained based on ET strategy. Finally, the effectiveness of the ET consensus criteria is demonstrated in the simulation section.
