Abstract
Although some advances have been made in addressing the bipartite consensus tracking problem for homogeneous multi-agent systems, achieving bipartite consensus tracking for heterogeneous multi-agent systems remains a challenge, especially in the presence of agent-actuator faults with unavailable time-varying control input and state information from the leader. To deal with this problem, a new kind of output-based adaptive distributed smooth observers are introduced to estimate the leader's state. Subsequently, fault-tolerant control protocols are designed and analyzed from a smooth output-feedback approach. Moreover, to reduce computational burdens, smooth control protocols based on reduced-order observers are constructed. It is proved that the multi-agent system driven by the designed control laws can achieve bipartite consensus tracking. Finally, the effectiveness of the theoretical results is validated through simulations. © 2025 Elsevier Ltd.
