Stabilization Control of Flexible Space Manipulator after Target-capture

中文摘要英文摘要

针对空间柔性机械臂目标捕获后基座位姿偏移、柔性臂杆横向纵向振动的问题,本文提出一种考虑臂杆多维柔性的空间柔性机械臂捕获后镇定控制策略。首先,结合假设模态法和拉格朗日法建立空间柔性机械臂与目标物组合体的运动学模型和动力学模型;然后,采用奇异摄动法对动力学方程进行解耦降阶,并以稳定基座位姿、抑制柔性臂杆振动为目标,设计组合体镇定控制策略;最后,通过仿真验证所提出组合体镇定控制策略的有效性。仿真结果表明,该镇定控制策略能有效调节捕获后基座位姿偏移和柔性臂杆的横向纵向振动,实现三维空间中组合体系统的镇定。

In order to solve the position and pose shift of the base, the lateral and longitudinal vibration of flexible links caused by contact-impact between the end of effector and the target in the task of target-capture,a method of stabilization control for flexible space manipulator considering the multi-dimensional flexibility is proposed in this paper. Firstly, the kinematics and dynamics model of combination for space flexible manipulator and target is built by assumed mode method and D-H parameter method; Secondly, the dynamic equations are decoupled by singular perturbation method, then the method of combination stabilization control is designed with the goal of stabilizing the base and abating vibration of flexible links; Finally, the effectiveness of the proposed method is verified by simulation. The result shows that the proposed method can effectively adjust the position and pose shift of the basStabilization Control of Flexible Space Manipulator after Target-capturee, as well as the lateral and longitudinal vibration of flexible links to achieve the stabilization of the combination system.
