针对被操作目标运动状态变化导致双臂与目标间内力发生突变的问题,提出了一种空间机动目标双臂协调柔顺操作控制方法.首先,针对空间双臂协调柔顺操作任务,分别建立双臂空间机器人开链动力学模型和闭链动力学模型;其次,考虑目标机动产生的扰动,设计阻抗参数自主调整策略,在双臂末端与目标间作用力发生较大变化时,可以保证双臂协调操作任务的平稳性和安全性;最后,搭建双臂协调柔顺操作地面物理试验系统,并开展物理仿真试验验证,试验结果表明了本文所提方法的有效性.
Dual-arm Coordinated Compliant Control for Maneuvering Orbital Targets
In order to cope with the sudden change of the internal forces between both manipulators and the target due to its unexpected maneuvering,a dual-arm coordinated compliant controller for maneuvering tar-get is proposed.Firstly,the open chain dynamics and the closed chain dynamics of dual-arm space manip-ulators are established,respectively,for dual-arm coordinated compliant operation tasks.Then,by taking into consideration the disturbance caused by the unexpected maneuvering of the target,the autonomous ad-justment strategy for the impedance parameters is designed,which can ensure the smoothness and safety of the dual-arm coordinated operation tasks in the case of significant changes of the internal forces between both the manipulators and the target.Finally,a physical simulation experiment system is deployed for du-al-arm coordinated compliant operation,and an experiment is implemented,which shows the performance of the proposed dual-arm coordinated transfer controller.
