WebAug 9, 2012 · 2.2. Dynamic optimization. A 3D walking simulation of 120% of a gait cycle was generated using a simulated annealing algorithm (Goffe et al., 1994) that fine-tuned the muscle excitation patterns and initial joint velocities such that the difference between the simulated and experimentally measured walking data (see below) and muscle stress … WebIn this paper, we have proposed a mathematical method to analyse human walking behaviour using dynamic optimisation. A main advantage of the method developed in …
WebOPTIMIZATION-BASED DYNAMIC HUMAN WALKING PREDICTION The approach is called predictive dynamics since the joint torques and angles are both treated as unknowns in the optimization problem. In addition, the cubic B-spline interpolation is used to represent the time history of the joint angle profiles and parameterize the optimization problem.
