In the mid-1900s, several technological and analysis concepts came together to make the PID controller widely accepted as an effective industrial controller. Discuss in detail and evaluate the performance of a PID or three-term controllers that are widely used in a typical paper mill where there may be about 2000 control loops, and over 90% of these would be PID control loops.
