Abstract

The invention provides a hand rehabilitation robot adaptive control method and device. The method includes obtaining an electroencephalogram signal characterizing user motion imagination and an upperlimb surface electromyogram signal characterizing user motion intention; performing feature extraction and classification recognition on the electroencephalogram signal, and obtaining the expected trajectory of hands; and inputting the expected trajectory into a variable impedance equation model, and obtaining the actual trajectory of the hands to obtain the motion-controlled quantity of each joint of a robot, wherein the impedance parameters of the variable impedance equation model can be adaptively adjusted according to the upper limb surface electromyogram signal. The method and device aresuitable for severe patients who cannot do upper limb motion or have small upper limb moving amplitudes; and adaptive adjusting can be performed on the impedance parameters of the variable impedance equation model according to the upper limb surface electromyogram signal, so that the adaptive control of the rehabilitation robot can be realized, and human-computer interaction levels during the rehabilitation training of patients can be greatly enhanced.

Description

technical field [0001] The present application relates to the field of rehabilitation robot control, in particular to a hand rehabilitation robot adaptive control method and device. Background technique [0002] At present, hand robot rehabilitation training methods are mainly divided into continuous passive motion therapy and robot-assisted rehabilitation therapy. Continuous Passive Movement Therapy (CPM) adopts the method of passive control. The main idea is to assist the patient's limbs to perform long-term passive movement through equipment to achieve the rehabilitation goal. This method often causes secondary injuries because of ignoring the patient's exercise limit, and Because patients do not have autonomy, they cannot carry out brain plasticity training, which greatly reduces the effect of rehabilitation treatment. Robot-assisted rehabilitation therapy adopts active control method, the main idea is to allow patients to actively participate in rehabilitation training...
