Adaptive Fixed-Time Control of Nonlinear MASs With Actuator Faults

IEEE/CAA Journal of Automatica Sinica, 2023
The adaptive fixed-time consensus problem for a class of nonlinear multi-agent systems (MASs) with actuator faults is considered in this paper. To approximate the unknown nonlinear functions in MASs, radial basis function neural networks are used.
