Abstract : This paper investigates a distributed consensus control problem for a class of uncertain nonlinear multiagent systems with hybrid faults. Most of the existing works about consensus control for multi-agent systems solely consider either actuator faults or process faults. Different from the works, the more comprehensive hybrid faults are proposed which mainly focusing on both process and actuator faults occur simultaneously. For the nonlinear multiagent systems with uncertainties, we propose a less conservative consensus strategy which relaxes the conservative condition on nonlinear terms. Subsequently, the novel distributed consensus strategy is proposed with the help of a backstepping design method. Based on the Lyapunov stability theory, it is proved strictly that the proposed controllers make the followers reach an agreement on a certain quantity of common interest. Finally, a simulation example is given to verify the effectiveness of the theoretical result.
