The industrial evidence is that for many control problems, particularly those of the process industries, theProportional, Integral andDerivative(PID) controller is themaincontrol tool beingused. Forthese industrial problems, the PID control module is a building block which provides the regulation and disturbance rejection for single loop, cascade, multi-loop and multi-input multi-output control schemes. Over the decades, PID control technology has undergone many changes and today the controller may be a standard utility routine within the supervisory system software, a dedicated ha- ware...
