Study on Response of Knee Rehabilitation Actuator using PID Controller

In this paper, we present the results of the study of the response of the knee actuator rehabilitation when use pneumatic and Arduino UNO controller. The dynamics and transmission functions of the actuator are set, the parameters selected, and the simulation responded by Matlab Simulink software. Simulation results show fast response time and low overshoot. Designed and manufactured mechanical parts and control circuits for the actuator. Human experiments were carried out, with experimental results giving a low error between the set value and the actual value, the settings of the set angle and the set cycle were easy to set up and the LCD display parameters. Exercise results are graphically represented by the Matlab software.
