Abstract: A type of intelligent control algorithm of course tracking for USV was proposed on the basis of RBF network approximation and compensation with input saturation. Firstly, sliding surfaces with integrator were designed on the basis of sliding mode control technology. Secondly, radial basis function neural network was applied to approximate compensating the system input saturation. Thirdly, second-order system observer was introduced to overcome the bounded outside interference. Finally, the control algorithm for USV was deduced by backstepping method with Lyapunov theory. Simulation result indicated that the intelligent control algorithm is suitable for USV.
