I have gone through several PID implementations and its tuning tutorials, documents and all. The Best tuning tutorial was PID-without-a-PhD.pdf . But has not been of much help. I can say it works some.
I want to perform it without the aluminium plate.
My question is how to start with graph plotting and all. I've seen and been attracted towards the graph only. Say take the PID-without-a-PhD.pdf file and just look at the plotted graphs. How to get that? which open tool to start with?
I have tried building and working on some self made graph plotting tool. The plotting against time is not satisfying, and hence the gain determination.
[If there are any self explanatory auto-tune algorithm available! : this is not my question now.]
I want to restart fresh with hard systematic approach. Any help will be god like helpful. I don't want to go with trail-n-error method. As that didn't help.
I am using AtMega2560, a coil, a stack of 2 neodymium magnet, a nicely working H-Bridge.
Also a hall sensor for feedback.
Now I have its transfer function with me. I am studying LTI Transient-Response Analysis using Python. The issue is I have a matrix of transfer functions. I might be wrong because what is called what, I don't know exactly. Will learn it soon.
