轨迹跟踪---船舶航迹控制，典型的欠驱动控制问题。两种算法，采用了matlab---simulink，直观明了。-Sailing ship trajectory tracking control, a typical under-actuated control. Two algorithms using matlab--- simulink, intuitive and clear.

实现航迹跟踪 得出仿真曲线 不会搭框图的可以学习下 一起学习(Realize track tracking to get simulation curve Can not take a block diagram can learn together Learn together)
