All in all... I think Spice will be a pretty awkward tool to do any
more than (1.). I'd look at something like University of South
Carolina's VTB (Virtual Test Bed). It's free, but closed source.
Unfortunately, I believe that the model will be more like #3. The power
source is a periodic hydraulic one. My ultimate task is to deliver peak
power from the mechanical system regardless of the available input power
(wave action). In addition to modeling the motor, I will need to model
the mechanical components. I looked briefly at the SC site, but it
requires a plug-in that I don't have.
How about setting up the differential equations of your dynamic model.
If you can formulate
them as a system of ordinary explicit de's and as initial value problem,
you can use a
Runge-Kutta method, that should be readily available as C-source (or at
least FORTRAN).
