Different from the traditional fault-tolerant control methods of autonomous underwater vehicle, the region tracking control theory was adopted, and the control target was designed as a spatial region. For the uncertainty and thruster fault in the system, the neural network was used to identify them online. Considering the problem of the divergence of neural network caused by the thrust saturation during the thruster fault, a neural network weight adjustment method based on a saturation factor was proposed. The effectiveness of the proposed method was verified by simulation.
