Abstract

In this article, the fixed-time bipartite consensus problem for multi-agent systems (MASs) under a structurally balanced topology graph is investigated. A novel fixed-time bipartite consensus control protocol is presented to address the convergence challenge in MASs with cooperative–competitive interaction. The control protocol enables MASs to achieve bipartite consensus within a settling time in any initial states. Moreover, the control protocol employs a dynamic event-triggered mechanism (DETM). Compared to the traditional static event-triggered mechanism, DETM entails lower controller update times, thus conserving communication resources more effectively. It is demonstrated that Zeno behaviours can be avoided. Finally, the effectiveness of the control protocol is validated through simulation examples.
