摘要: 研究双臂空间机器人捕获目标过程的动力学控制和仿真。利用第二类拉格朗日方程建立空间机器人动力学模型,并基于动量定理,计算捕获目标过程机器人漂浮基座和机械臂运动状态受到的碰撞影响效应。针对捕获目标后形成的闭链系统,设计力/位形协调控制算法对系统的运动状态和目标的夹持内力进行控制,以保证捕获过程系统的稳定性、可靠性和安全性。基于动力学模型和控制算法进行数值仿真,仿真结果验证了上述控制算法的有效性。

Abstract: The dynamics control and simulation of dual-arm space robot capture object was studied. The dynamics model of space robot was derived by the second Lagrange equation, for the object capture process, the impact influence on space robot base and arm was calculated by momentum theory. For the space robot and object close-chain system after capturing, a force/position coordinate control algorithm was designed to control the system motion and object clamp force; the stability, reliability and safety of capture process would be ensured by the control algorithm. The simulation result based on the dynamics model and control algorithm was carried out. The result indicates the validity of above analysis.

Key words: dual-arm space robot, capture object, impact, close-chain system, force/position control
