摘要

本文研究了机械臂机器人系统抓取和处理物体的协同控制。基于被动分解方法,将合作系统分解为解耦的形系统和锁定系统。然后,提出了解耦形锁系统的无回归自适应控制律。尽管已有的文献中的形状和锁定方法,该方法保证了当机器人动力学未知时闭环系统的无源性。仿真结果验证了所提控制方案的准确性。

Cooperative control of manipulator robotic systems with unknown dynamics
Cooperative control of manipulator robotic systems to grasp and handle an object is studied in this paper. Based on the passive decomposition approach, the cooperative system is decomposed into decoupled shaped and locked systems. Then, regressor free adaptive control laws for the decoupled shaped and locked systems are proposed. Despite existing shaped and locked approaches in the literature, the proposed approach guarantees the passivity of the closed loop system when the robots dynamics are unknown. Simulation results verify the accuracy of the proposed control scheme.
