Hello !
I’m writting a paper including a description of the model I developed. In this model I used the FDK algorithm.
I would have been interested in explaining FDK in detail. My idea was to create a process scheme as the one attached.
Here is a short explanation (based on my understand 
)
As an inverse dynamic problem, positions of the segments are the input variables (q). They are derived twice (velocity \dot{q} and acceleration \ddot{q}) and used to solve the motion equation.
From motion equation, muscular (F^(MT)) and reaction forces (E) are calculated.
Two cases :
- If there is NOT a quasi-static equilibrium between forces and position of segments refered in the FDK, then q_{FDK} is updated and a new iteration of the same process begins.
- If there is a quasi-static equilibrium between forces and position of segments refered in the FDK, then go to the next step.
Could you give me your opinion about :
1/ if the scheme/explanation are right !
2/ if the scheme/explanation are clear enough
Thanks a lot for your support !
