Python & PID Controlled Magnetic Levitation

It can be tough to find detailed information about electromagnetic simulations online – at least as things stand in the present internet. Where information is present it is provided in some standard form as outlined by textbooks and it is not always immediately apparent how this textbook knowledge can be translated into implementations. In this article, I build a very simple and maybe inaccurate PID control system that very superficially pretends to run on a microcontroller. To support this, since I don’t have a real system to test on, I outline a very quick and dirty approach to modeling electromagnetic levitation of a set of coils above a track using python and a recently developed package: Magpylib.
