摘要

本文讨论了基于自适应退步法的海船自适应保持航向控制系统的设计问题。该控制器在设计阶段既考虑了舵机的动态特性,又考虑了舵机的全非线性静态操纵特性。利用遗传算法对所实现的非线性控制结构的可调参数进行整定,以优化系统性能。采用B-481型船舶全尺寸仿真模型,考虑了波浪和风的影响,采用时域分析方法对控制算法进行了仿真。

Designing a ship course controller by applying the adaptive backstepping method
The article discusses the problem of designing a proper and efficient adaptive course-keeping control system for a seagoing ship based on the adaptive backstepping method. The proposed controller in the design stage takes into account the dynamic properties of the steering gear and the full nonlinear static maneuvering characteristic. The adjustable parameters of the achieved nonlinear control structure were tuned up by using the genetic algorithm in order to optimize the system performance. A realistic full-scale simulation model of the B-481 type vessel including wave and wind effects was applied to simulate the control algorithm by using time domain analysis.
