为克服船舶过冲引起的航迹偏差等缺点，还设置了适当的训练目标。

The appropriate training targets are set to lessen the tracking error being caused by overshoot and other undesirable characteristics.

可在参数窗口中任意更改航迹偏差带、操作方式等参数，采用PID控制算法进行了船舶航迹控制仿真。

Parameters such as track error band and steering mode can be modified arbitrarily in the parameter's window. The simulation of ship motion control is carried out with PID algorithm.

针对原系统图形换屏显示时船舶航迹有时位于屏幕一角及航迹偏差带有时宽窄不一致的问题，重新设计了换屏技术及采用了新的偏差带的画法，根据船舶运动计划航线决定船舶进入屏幕的点，保证了船舶位于屏幕中部。

A new method of changing screen is adopted and the point where ship drives into the screen is determined in accordance with the ship's course to make the ship located at the middle of the screen.
