Abstract
In this paper, we investigate the output synchronization problem for a nonlinear multi-agent system class that involves unknown parameters, disturbances, and unknown control coefficients. At the same time, the use of switching threshold event-triggered control not only reduces the computational load and controller update frequency but also balances the system performance. Combined with prescribed performance control, the transient performance of the system is improved as well. Compared with previous studies, the controller proposed in this article ensures that, in the absence of leader, the neighborhood error of each agent evolves within the specified range and eventually tends towards 0 rather than evolves within a residual range. Finally, the effectiveness of the proposed approach is verified through numerical simulations.
期刊介绍：
Founded in 1981 by two of the pre-eminent control theorists, Roger Brockett and Jan Willems, Systems & Control Letters is one of the leading journals in the field of control theory. The aim of the journal is to allow dissemination of relatively concise but highly original contributions whose high initial quality enables a relatively rapid review process. All aspects of the fields of systems and control are covered, especially mathematically-oriented and theoretical papers that have a clear relevance to engineering, physical and biological sciences, and even economics. Application-oriented papers with sophisticated and rigorous mathematical elements are also welcome.
