Abstract

The invention provides a system for assisting arm movement, which can suppress and alleviate the user's tremor behavior. The system includes: a detection module, a control module, an actuator, and a power supply module for supplying power to the detection module, the control module, and the actuator; wherein, the detection module is used to detect the motion feedback signal of the user's arm; the control The module is used to analyze the detected motion feedback signal of the user's arm, and use the signal separation algorithm to filter the analysis result to obtain the tremor signal of the arm. According to the obtained tremor signal of the arm, use the feedforward control strategy and the PID controller to The executive mechanism performs control, wherein the PID controller represents a proportional, integral and differential controller. The invention relates to the field of sensing measurement and electronic control.

Description

technical field [0001] The invention relates to the field of sensing measurement and electronic control, in particular to a system for assisting arm movement. Background technique [0002] Parkinson's disease (Parkinson's Disease, PD) is a neurodegenerative disease that leads to the gradual loss of the brain's ability to control muscles, but so far, the real cause of Parkinson's disease has not been found. [0003] The well-known main obvious symptom of Parkinson's disease is resting tremor. In addition, patients will also have symptoms such as muscle and joint stiffness, stiffness of body parts, slow movement and poor balance. As the number of patients with Parkinson's disease is increasing year by year, the data shows that the growth rate of the number of Parkinson's patients in my country has entered a stage of rapid growth, which not only adds great pressure to the patients themselves, but also brings great pressure to the patients' families and society. come a heavy bur...
