Abstract :
In this paper, the relationship between the gait and the valve opening of pneumatic passive prosthesis is studied. Four-bar linkage with a fixed pneumatic cylinder was adopted as the mechanism of the prosthesis joint. A fuzzy control rule is proposed base on the changes of the gait cycle in different walking speed. The experiments show that the gait cycle can control the needle valve to achieve the adjustment of pace. The control method for walking speed adjustment is feasible.
