MH's ideal coil and voltage question

.99,

I added the following to my post you referenced:

If Partzman wants to attempt this, do you have any better or simpler suggestions as to how he might to go about it?

These two references (I prefer the approach with the green schematics (pspice), last page):

Should not be difficult.

Do you have a scope,or access to one?

I have a very well equipped bench including a Tek MDO3034 scope with math and FFT capability. What do you have in mind?

PW and Poynt,

I still have family visiting so I have glanced thru the posts quickly and will have to follow up later as time permits. I am willing to give the sim a go.

Do you seriously believe that many will accept, or even recognize, those models as being similar to the model being discussed?

I was looking for something much simpler and easily recognized as the actual model at hand.  How about this:

A fixed Vsource set to 4V is used for the applied EMF and a voltage controlled Vsource is used for for the CEMF.  The CEMF Vsource is selected so that 1 volt on the control input equals 1 volt on the CEMF Vsource output.

For a di reference current, Iref, an ideal 5H inductor is simultaneously connected to a second fixed Vsource of 4 volts and the current measured thru that inductor is used as Iref.  The current flowing thru the model is detected, Idet, and a comparator function is used to generate an error voltage to control the CEMF's Vsource.

I think most people would be able to recognize this as being similar to the inductor model and the CEMF voltage can be measured directly, or by proxy, via the 1V:1V CV input.

I would be most concerned with how to control damping/ stabilizing the loop.  Your thoughts regarding that, and this concept in general, would be most appreciated.

No, I do not. That is why I changed my mind about doing it, as I mentioned. But with all due respect what you are proposing is pointless as well, in my opinion, because it won't be accepted, especially since you are proposing to use an ideal inductor as part of the model (this in itself is part of the contention).
