Global Prescribed Performance-based Fault-tolerant Control for Trajectory tracking of the ACV with uncertainty

This paper focuses on a fixed-time prescribed performance-based Fault-tolerant controller that guarantees the global performance for Trajectory tracking control of air cushion vehicle (ACV). In presence faults, time-varying parameters and environmental disturbances, proposed system in this has good robustness performance. Firstly, an integrated observer disturbances faults is to suppress all uncertainties system. Then novel function designed does not need be constrained by initial value target errors while ensuring it convergence Global advantage separating error conditions from function. At same time, combined with sliding mode method, fast whole are guaranteed. Finally, simulation results verify effectiveness
