Abstract

This paper addresses the issue of end-effector trajectory tracking control of multi-link flexible joint robot manipulators. A submanifold is designed to describe the ideal trajectory tracking performance. Dynamics of the robot is rewritten in terms of the manifold. Control schemes are derived using backstepping control design approach. Stability of the system is analyzed based on Lyapunov stability theory. Simulations are carried out to on a 2-link flexible robot manipulator. The results demonstrate effectiveness and usefulness of the proposed control method.

基于反步法的柔性关节机器人工作空间轨迹跟踪控制
研究了多连杆柔性关节机器人的末端执行器轨迹跟踪控制问题。设计了一个子流形来描述理想轨迹跟踪性能。机器人的动力学被改写成流形的形式。采用反步控制设计方法推导控制方案。基于李雅普诺夫稳定性理论分析了系统的稳定性。对一种二连杆柔性机器人机械手进行了仿真。结果表明了所提控制方法的有效性和实用性。
