船摇前馈控制补偿效果及优化方法研究

雷达隔离船摇的主要手段之一.针对船摇前馈在实际工程应用中补偿效果不理想的问题,通过对前馈复合控制原理、船摇前馈实现方法和效果影响因素的研究,提出了工程实现的优化方法.采用时间序列分析方法进行船摇数据预报可以提高近一个数量级的预报精度,从而直接提高船摇前馈补偿量的计算精度和补偿效果.通过在前馈补偿环节中加入自适应设计以实现船摇前馈信息有效平稳地加入控制环路.此外,选择适宜的时机加入船摇前馈也是工程应用的一个重要因素.

Study on compensating effect and optimizing methods of ship-sway feedforward control

Feedforward control is an important method of ship based radar to eliminate disturbance of ship's sway.Aiming at the problem that ship-sway feedforward control cannot take satisfactory effect in engineering practice,this paper studies such issues of principle of feedforward compound control,realization method and the factors which influence the compensating effect.The methods of engineering implementation to improve the effect are put forward.The ship-sway prediction method based on time series model can ma...
