FLORIANO BATISTA, Rayanne; ABREU GARCIA, José Rafael  e  FERNANDEZ CASTANEDA, Feliberto. Model system for the control of knee prosthesis transfemoral for a cycle of walk. EAC [online]. 2012, vol.33, n.2, pp. 42-49. ISSN 1815-5928.

This paper presents the design of a model for the control system of a knee prosthesis, in a cycle of human gait. The model is simulated through computational tools such as Simulink and SimMechanics, in this case, considering the biomechanical model of the pendulum double as a representation of the human leg and based on the parameters of the anthropometric. Through the analysis and study of human walking normal develops a method of control and identification of the phases of the cycle of human gait, to act in the articulation of the knee with use of a transfemoral prosthesis. Among the major findings, it emphasizes the achievement of a precise control of the position during the flexion of the knee, which gives it a development of the process of progress with the prosthesis very similar to the normal running.
