Abstract

The invention relates to the technical field of robots, and discloses a method for compensating friction force or friction torque. The method for compensating the friction force or the friction torquecomprises the steps that the current output force / the current output torque of a controller in a closed-loop control system is obtained, the previous friction force / friction torque is compensated according to the current output force / the current output torque, and the current friction force / the current friction torque is obtained, the current output force / current output torque is compensated according to the current friction force / current friction torque to obtain a force control value / torque control value, and the actuating mechanism is controlled according to the force control value / torquecontrol value. By adopting the method for compensating the friction force or the friction torque, the friction force can be compensated more quickly. The invention further discloses a device for compensating the friction force or the friction torque and a rehabilitation robot.

Description

technical field [0001] The present application relates to the technical field of robotics, for example, to a method, device and rehabilitation robot for compensating friction force or friction torque. Background technique [0002] At present, patients with joint injuries, nervous system injuries, skeletal muscle injuries, etc., lead to joint skills impairment, and patients need rehabilitation training to restore or improve joint function. Rehabilitation training includes patients actively completing a series of training actions, patients completing a series of training actions with the assistance of a rehabilitation therapist, or patients completing a series of training actions with the assistance of auxiliary equipment. [0003] The Chinese utility model patent whose authorization notification number is CN206063380U provides an upper limb rehabilitation training machine, which includes a hand rest and a movable board for supporting the upper limbs, the hand rest is arranged...
