Thank you all so much for the quick replies! We sourced an alternator to start experimenting with and if that fails, we'll look into SelSyn motors.

My apologies if my terminology is not exactly correct, my background is more in embedded programming. My colleague and I are in the feasibility stage of a project to build a scale model of a hydro-electric dam as a teaching aid for our students. We need two small three phase generators with...

It's no problem at all. Luckily I do remember enough to have a certain amount of intuition about the topic!

Ok, so I got a chance to play around with adding the lowpass filter. I can now plot the controller output, which is great! When you said "Kf=10 gives pretty good results with the PID you have above", did you mean Kf=0.1? At Kf=10 the cutoff is 0.1 [rads/s] which is pretty low. My system shows...

Thank you for the helpful response! Although I don't remember all the details surrounding causality, linearity, time invariance, phase and gain margins, root locus analysis, etc, I do remember the overarching themes of the controls classes I took. Your reply has given me enough info to move...

Hello. I'm sorry this post is so wordy, but I wanted to make sure I explained myself as well as I could. I am trying to clear some of the cobwebs and re-learn some of the controls material from my school days. I'm using Octave to run step tests on systems. So far, I've been able to plot the...
