Influence of the controller design on the accuracy of a forward dynamic simulation of human gait [PDF]

, 2017
The analysis of a captured motion can be addressed by means of forward or inverse dynamics approaches. For this purpose, a 12 segment 2D model with 14 degrees of freedom is developed and both methods are implemented using multibody dynamics techniques ...
