Mathematical design of energy-optimal femoral prostheses

Journal article, 2001

A new formulation of the problem of designing a femoral prosthesis is proposed. This formulation reduces to solving the problem of the energy-optimal control with pa- rameters for a nonlinear multidimensional mechanical system that models the human locomotor system with a femoral prosthesis. The results of numerical solution of the optimal control problem for two types of prostheses with pneumatic and hydraulic knee mechanisms are described.
