摘要:

为解决未知环境下环境参数的不确定导致的机器人恒力打磨自适应调节能力不足的问题,提出一种未知环境参数实时估计的机器人自适应变阻抗恒力控制方法。该方法将自适应滑模控制作为内环控制,将环境参数估计与自适应变阻抗控制作为外环控制。机器人平台实验结果表明,所提方法能较好地实现期望打磨力跟踪,对未知环境工况机器人打磨作业具有较高的自适应性。

Abstract:

To solve the problems of insufficient adaptive adjustment ability of robotic constant force grinding due to the uncertainty of environmental parameters under unknown environments, a robotic adaptive variable impedance constant force control method with real-time estimation of unknown environmental parameters was proposed. In the proposed method, the adaptive sliding mode control was used as the inner loop control, and the environmental parameter estimation and adaptive variable impedance control were used as the outer loop control. The robotic platform experimentsal results show that the proposed method may realize the tracking of the expected grinding forces, and has high adaptability to the robotic grinding operations under unknown environmental conditions.

Key words: robotic grinding, constant force control, adaptive variable impedance, environmental parameter estimation
