Well done Ron!


I'd like to add one thing though. In the real world there are times when proportinal only control does work. Any time you have cascaded control loops it is possible that a proportional only loop can be the best fit for one of the loops, ie:

P Loop -> PID Loop

It doesn't tend to work as well if you try to invert it, but I won't say that it will never work, ie:

PID Loop -> P Loop
