Abstract

The invention discloses a self-adaptation training control method of a parallel lower limb rehabilitation robot and the rehabilitation robot. The method comprises the steps that lower limb muscle activity and contractility state are estimated according to collected electromyographic signals and impedance model parameters of the robot are adjusted in a self-adaptation mode according to the lower limb muscle activity and contractility state; meanwhile, interaction acting force between a patient and the robot is obtained, and calculation and correction of the motion of the robot are achieved through a recognition result and an impedance model; a master control portion of the rehabilitation robot provides online trajectory planning and inverse kinematics, control instructions are sent to a controller and a driver of a corresponding joint, and self-adaptation training control over the robot is achieved. Intelligentization can be achieved in the rehabilitation process, and the fundamental practical significance and application value for improving the patient rehabilitation effect and improving the patient rehabilitation initiativeness and motivation are achieved.

Description

technical field

[0001] The invention relates to the field of control of auxiliary medical rehabilitation robots, in particular to an adaptive training control method based on muscle state evaluation of a parallel lower limb rehabilitation robot. This method collects the surface electromyographic signals of the lower limbs of the human body and evaluates the contraction force state of the relevant muscles online through processing and calculation, so as to adaptively adjust the parameters of the human-machine impedance model, and drive the rehabilitation robot to assist in training with different degrees of compliance. The method of the invention is applicable to fields such as medical rehabilitation robot and artificial limb control. Background technique

[0002] The rehabilitation of the elderly, the disabled, and people with limb movement disorders caused by stroke and hemiplegia has become an urgent social problem. The traditional rehabilitation of limb dysfunction mainly...
