Abstract:	This paper proposed a novel adaptive cooperative fault-tolerant tracking control method for nonlinear multi-agent systems (MASs) subject to actuator faults, limited communication bandwidth and unknown control gains. First, a distributed high-order sliding mode observer is adopted to estimate leader’s state, which can also identify some unknown and uncertain malicious attacks. Second, a new tracking error transform mechanism is presented, and it is applied to change the constrained error to an unconstrained tracking error. Fuzzy logic systems are employed to estimate the unknown nonlinearity function in the MASs. Then, a fixed-time prescribed performance function is designed to achieve the stable tracking performance. By using the developed method, it is proved that the tracking errors of thus a multi-agent system can converge into a small neighborhood within the fixed time. Finally, simulations illustrate the effectiveness of the proposed control method.
