坐标变换
Examples
- Change of coordinates
坐标轴的变换 - Taking triangular - windows of car seal for an example in the article , in combination with the feature of car seal of reverse engineering and the theory of change of coordinate , the software of reverse engineering was adopted to realize alignment between the cloud data and section data of car seal
以汽车密封条三角窗产品为例，结合汽车密封条产品逆向工程的特点和坐标变换的理论，利用逆向软件，实现了汽车密封条点云数据与截面数据的对齐。 - 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。
