摘要:

在本文中,我们提出了一种新的安全,被动,鲁棒控制律的机械系统。所提出的方法从物理人机交互的角度解决了安全问题,其中机器人不仅必须停留在预定义的区域内,而且必须遵守速度约束,并确保相对于可能由人类或环境引起的外部扰动的被动性。所提出的控制是以封闭形式编写的,即使在奇异配置期间也表现良好,并且只要安全要求(例如,速度(velocity)。所提出的方法是在一个6自由度机器人上实现的,以证明其有效性,在一个物理的人机交互任务。

英文摘要:

In this paper, we propose a novel safe, passive, and robust control law for mechanical systems. The proposed approach addresses safety from a physical human-robot interaction perspective, where a robot must not only stay inside a pre-defined region, but respect velocity constraints and ensure passivity with respect to external perturbations that may arise from a human or the environment. The proposed control is written in closed-form, behaves well even during singular configurations, and allows any nominal control law to be applied inside the operating region as long as the safety requirements (e.g., velocity) are adhered to. The proposed method is implemented on a 6-DOF robot to demonstrate its effectiveness during a physical human-robot interaction task.
