A regenerative prosthesis is modeled and simulated. The simulation is optimized with the biogeography-based optimization algorithm to obtain desired knee angle tracking with a reference knee trajectory and to regenerate energy. The prosthesis is able to track a reference knee angle with a 5.1 degree error averaged over an entire stride and regenerate some energy throughout the stride.

Traditional, passive leg prostheses for transfemoral amputees require the user to produce unnaturally large actuations in order to walk. The resulting motions can cause joint degeneration and arthritis. To avoid this, a semi-active prosthetic knee using hydraulics to store and release energy has been developed. In our work this summer, we have improved upon a previous simulation model for this leg, and we have developed preliminary valve control results in this simulation software with BBO.
