I've always been fascinated in how the process actually occurs. Is it more or less handled by software these days or are you performing the calculus yourself? What applications are you tuning? Cheers!

Not so much anymore but at my last couple jobs I did a lot of PID (actually PI) tuning. It was for chemical control so very slow action. I never really did any math unless I was having a particularly tricky time. Usually I would just tweak the gains manually based on trend data
