pid control wiring & setting

What follows is a very instructive article on a PID temperature loop control example by Wayne Salo over at ExcelEngineering in the St. Paul, MN area.  It shows how temperature control can start as a fairly simple system,

but over time (and as learning takes place) the control can get fairly complex as the desire for tighter control increases aswas the case in this project.

The project was posted as 4 separate Blog articles over a period of time starting

I’m republishing these articles here so the reader can see the progression of solutions offered, all to achieve increasing levels of control needed for what turned out to be a tightly controlled application using process knowledge, feed forward, and a cascaded PID control
