Abstract : A large process industry can have somewhere between five hundred and five thousand control loops, and PID controllers are used in 90–97% of the cases. It is well-known that only 20–30% of the controllers in the process industry are tuned satisfactorily, but with the methods available today it is considered too time-consuming to optimize each single controller.

2. Design of Robust PID Controllers with Constrained Control Signal Activity
Abstract : This thesis presents a new method for design of PI and PID controllers with the level of control signal activity taken into consideration. The main reason why the D-part is often disabled in industrial control loops is because it leads to control signal sensitivity of measurement noise. READ MORE
