2 suggestions for motion control revolve around what you want to do.
We have used Creonics boards and been trying to replace them with
a solution of our own.  In our experience the Creonics was not
sufficient for what we were trying to do: Control a six axis manipulator
whith (slightly) unusual dynamics.  The Creonics would have been
wonderful for a process automation environment with less dynamic
constraints.  For high performance applications I would reccomend
the new DSP based multi-axis MC board from Delta-Tau motion controls.
This seems to be able too control many different types of motors and
several different types of amplifiers and feedback.  Dual ported memory
is the interface (as with the Creonics).  The board has some facility
for digital filtering and I think you can also modify the control law
structure somewhat (I don't have the info yet).

If you want to have a more detailed conversation about
optimal control systems you should tell us a bit more about
your application.
