This course introduces basic knowledge of Analytical Mechanics and theory of movement stability, and focuses on dynamics knowledge related tightly with engineering technique such as orbit moment in central gravitation field, electromechanical coupling dynamics, rigid-body dynamics, gyroscopic dynamics, manipulator dynamics et al.

本课程较系统地叙述了分析力学和运动稳定性理论的基础知识，着重介绍与工程技术密切相关的动力学知识，如中心引力场中的轨道运动、机电耦合系统动力学、刚体动力学与陀螺力学、机械臂的动力学分析方法。

Firstly, the reduced dynamic model including motor dynamics is developed for mobile manipulators. The system is then decomposed into four lower-dimensional subsystems by applying diffeomorphism and nonlinear input transformation to the reduced model. The design of the second order dynamical sliding mode controller is then addressed for the output tracking of mobile manipulators.

首先给出了包括驱动电机动态特性的移动机械臂的简化动态模型，然后通过微分同胚和输入变换将其分解为四个低阶子系统，并给出了其输出跟踪的二阶动态滑模控制器的设计方法。

Communication through the world circumvents the problem of calibrating the vision system with data from the arm, Brooks wrote.

通过外部世界进行的沟通可以避开根据来自触臂的数据调校视觉系统的问题。布鲁克斯写道。

Their eyes are at the tips of their arms and are protected by a circle of spines.

The height of swing arm is regulated by the handwheel at the top of the machine and the cutting stroke is regulated by the timer so as to easily obtain optimal cutting position to improve work efficiency and prolong the service life of die cutter and padding plate .

摆臂的位置高低由机器上端的手轮调节，冲裁行程由时间计时器调整，这样可以轻易获得最佳裁切位置，提高了工作效率，延长了刀模和垫板的使用寿命。

In fact, from a vantage point that viewed our galaxy face-on, astronomers in distant galaxies would likely see the Milky Way as a two-armed barred spiral similar to this artist's illustration.

事实上，如果天文学家从一个有利的位置朝我们银河系观看，那么从遥远星系上看到我们银河系是一个具有两条旋臂的棒旋星系，就像这张艺术家的插图一样。

However,this kind of structures has a very low iriherency frequency,and easy to vibrating.So it is important to pay more attention to research on the FRM.

而这种结构具有极低的固有频率，在运动时或定位时容易产生弹性振动，影响运动平稳性和定位精度，因此柔性机械臂的控制研究具有特别重要的意义。

The simulation results show that the control strategy has a good result on the vibration reducing of flexible manipulators.

实例仿真的结果表明，该控制方案能有效地抑制柔性臂的弹性振动，具有良好的控制效果。
