Is anybody interested?

Do you have a simulator, or are you asking if someone else does?

How adaptable would the simulator be to other servo problems?

How would it deal with the bulk modulus of the hydraulic fluid, and the stiffness of whatever structure is in the loop?

IRstuff knows I am a long time Mathcad power user but mathcad is no longer worth upgrading.
Python is free and object oriented so one can instantiate multiple instances of an object from a class definition. Mathcad requires a lot of cut and paste.
I have had the simulator below for years. I use it about once a month for solving real problems.

IRStuff, are you referring to servo motors?

I chose python because it is free, easy to read, modern and has pretty good scientific calculation abilities like Matlab. I do miss the symbolic math of Mathcad or Mathematica.

Yes, to the servo motors

and, I would think you'd be missing the units thing, too ;-) Although, Mathcad Prime 5 or 6 should be getting close to where M15 is/was
