摘要
返回原航迹机动在航行中营救落水者、海上搜救、扫布雷等舰船机动中经常使用,但目前采用的方法属常规方法,未考虑风、流、浪等因素的影响,对大多数舰船而言存在精度问题。本文结合舰船操纵运动数学模型,充分考虑到舰船的旋回惯性和环境因素的影响,利用优选法选择操舵时机,提高了舰船返回原航迹机动的精度。
Turning onto the reciprocal course is often used for recovering a man overboard and mine sweeping at sea. Because the general method,such as the Williamson Turn, does not take the wind, current and wave into account, sometimes the precision is not so good. In this paper, basing on the maneuvering mathematical model, we consider the influence of environments, then choose the opti-mum rudder＇s shifting time by the use of optimum seeking method. The result of simulation show that this method can improve the precision of turning onto the reciprocal course.
