对微机械臂受力分析得到运动学方程，求解后得出微机械臂的关节力矩和宏机械臂末端作用力的关系。在已知柔性臂末端的弹性变形和振动情况的基础上，用PD控制原理使微机械臂关节产生所需力矩(The kinematics equation of the mechanical arm was obtained. The relationship between the joint torque of the micromanipulator and the end force of the macro manipulator was obtained. On the basis of the elastic deformation and vibration of the end of the flexible arm, the PD control principle is used to make the torque required for the micro manipulator joint.)
