摘要/Abstract

摘要： 全柔性空间机械臂捕获卫星后会产生柔性振动,同时导致系统处于不稳定状态。本文针对不稳定的混合体系统,提出了基于混合轨迹的自校正控制算法,以完成镇定运动控制。该方案利用梯度下降法思想,设计了参数的自适应律,实时调节PID控制器控制参数。根据李雅普诺夫函数,设计了监督控制器以保证控制系统的稳定性,使其具有H_∞跟踪特性。之后,基于虚拟力概念生成混合轨迹,用于实现关节运动及柔性振动抑制的一体化控制。最后,通过数值仿真实验证明了上述控制方案的有效性。

关键词: 全柔性空间机械臂, 捕获操作, 混合轨迹, 自校正PID控制

Abstract: The flexible vibration is generated after all-flexible space manipulator capturing a satellite, and the collision leads to unsteadiness of system. For the unstable composite system, the self-turning control algorithm based on hybrid trajectory is designed in this paper. The theory of gradient descent is used for parameter adaptive rate design to realize the real time adjustment of the PID control parameters. A supervised controller is designed through Lyapunov function to generate the stability and H_∞ tracking characteristic of the system. The hybrid trajectory is generated based on the concept of virtual force, which is used to accomplish integrated control of joint movement and vibration abatement. At last, the effectiveness of the proposed control scheme is demonstrated through numerical simulation.

Key words: all-flexible space manipulator, capturing operation, hybrid trajectory, self-turning PID control
