Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

Machines and processes are controlled using many strategies, from simple ladder logic to custom algorithms for specialized process control, but proportional-integral-derivative (PID) is the most ...

What Are PID Controllers? PID control is the most commonly used control algorithm, used extensively in industrial, process, and commercial applications and has been universally accepted as the easiest ...

So far we have discussed the PI tuning problem in the context of a linear system. This is because under steady-state conditions when the system transients settle out, you will probably be operating in ...

We are now on the eight part of a ten part series about teaching your PI controller to behave like you want it to. At the heart of this discussion is a proposed tuning technique which allows you to be ...
