Abstract

Knee joint is the most important and complex structure in human lower limbs. It is a nonlinear, time-varying and strong coupling system. In this paper, the mechanical structure of prosthetic knee joint is built, and parallel control of CMAC and PID algorithm is introduced to establish the knee joint control model. Through the simulation analysis, it is found that CMAC-PID control algorithm compared with the traditional PID control can improve the real-time and accuracy of the system. Therefore, CMAC-PID control algorithm can optimize the control effect of the prosthetic knee.
