摘要
针对直线不稳定船舶的全局直线航迹控制,提出了一类航迹非线性状态反馈控制算法。采用Lya-punov直接法分析系统的稳定性,得到了保证闭环控制系统全局渐近稳定的充分条件,从而解决了直线不稳定船舶航迹闭环控制系统全局稳定性的判定问题。数值仿真和模拟试验结果验证了该充分条件的正确性。
A nonliear state-feedback control law is proposed for global straight-line tracking control of unstable ship dynamics. Based on Lyapunov＇s direct method, the sufficient conditions of global asymptotical stability are obtained for the closed-loop system, this conditions solving the problem of global stability test for tracking control system of unstable ship dynamics. Simulation and experimental results vexify the proposed sufficient conditions.
