Bruno Chareyre proposed the following answer:
One possible strategy is to simply impose a force on the top plate and let it
equilibrate (it needs to have a mass).
Is is simple but it does not offer the best control usually, due to the
inertia of the plate.
Another strategy is to impose de velocity (or displacement): v = f(sm-st), with
"sm" the measured force and "st" the target force.
The remaining question is how to define f. One way is to calculate the
cumulated stiffness K of all plate-particle interactions, and to use it in:
v=(sm-st)/(K*O.dt)
which will produce a nearly constant force.
