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.
本文研究了欠驱动水面舰艇的航向控制问题。首先,采用神经网络来确定理想虚拟反步控制未知部分的参数,甚至神经网络的权重值也通过自适应技术进行更新。然后,通过李雅普诺夫稳定性理论证明了航向跟踪误差收敛的一致稳定性。最后,进行了仿真实验以说明所提控制方法的有效性。
