摘要

本文研究了一种三自由度并联驱动机械臂的位置/力混合运动控制方法,并将其应用于间隙约为10 /spl μ m的钉孔任务。该控制系统由力反馈驱动的底层位置伺服系统组成。控制只需要计算逆运动学,这对于并联机械臂来说非常简单。在操作员的辅助下,通过使用基于力-扭矩的操纵杆命令和/或预先规划的运动数据来产生运动。在遥操作模式下,操作人员可以干预并在预先规划的搜索运动上叠加校正运动。

Kinematic hybrid position/force control of a 3-DOF in-parallel actuated manipulator
The paper aims to describe kinematic hybrid position/force control for a three-degree-of-freedom (3-DOF) in-parallel actuated manipulator, and its application to peg-in-hole task about 10 /spl mu/m clearance. The control system consists of a low-level position servo driven by force feedback in base coordinates. The computation required for the control is only inverse kinematics, which is very simple for the parallel-link manipulator. Assisted by a human operator, the motion is generated by using force-torque based joystick commands and/or preplanned motion data. In teleoperation mode, the human operator can intervene and superpose corrective motions over the preplanned searching motion.
