船舶航迹控制中航迹段的确定

The Definition of the Track Passage in Ship Track-keeping Control

在进行航迹控制时,必须确定当前船位与设定航迹的相对关系。由于设定航迹是由多个转向点之间的航迹段连接而成的,因此必须确定当前船位所跟踪的航迹段。此文提出一种算法,将航迹段再进行分段,确定当前船位在设定航迹上的相关点,从而确定应跟踪的具体航迹段。

During the track-keeping control, the relativity between the current ship position and the set track must be confirmed. Since the set track was connected by many track passages which were between two adjoined waypoints, the definite track passage that the current ship position is keeping must be confirmed.The paper provides an algorithm which subdivide the track passage and fix the correlative point on the set track and fix the definite track passage that the current ship position should keep.
