Course Control of Underactuated Ship Based on Nonlinear Robust Neural Network Backstepping Method

الملخص EN

The problem of course control for underactuated surface ship is addressed in this paper.

Firstly, neural networks are adopted to determine the parameters of the unknown part of ideal virtual backstepping control, even the weight values of neural network are updated by adaptive technique.

Then uniform stability for the convergence of course tracking errors has been proven through Lyapunov stability theory.

Finally, simulation experiments are carried out to illustrate the effectiveness of proposed control method.
