• In ship steering controller design , the nonlinear ship model should be written in siso strict feedback form . we start the recursive design with the system first state variable and continue with the second one . by introducing a change of coordinates , we choose lyapunov functions to stabilize the system and obtain the control law
  在船舶航向控制方面，考虑船舶的稳态回转非线性，应用backstepping方法设计：首先把系统化成单入单出的严格反馈控制形式(呈下三角结构) ，假设系统后一个状态变量是前一个状态变量的虚拟控制，通过适当的变量代换，在每一步构造李亚普诺夫函数，使前一子系统在虚拟控制下渐近稳定，逐步递推出控制器控制规律，使整个系统在平衡点满足一致渐近稳定性。
