Advanced regulatory control seeks to incorporate knowledge of process dynamics, disturbances, constraints, and objectives to increase process efficiency and capacity. The PID power and flexibility enables an incredible spectrum of creative opportunities to achieve these goals. Here we look at techniques to preemptively deal with upsets and setpoint changes, protect against abnormal conditions, improve process linearity, compensate for dead time, eliminate limit cycles, reduce valve deadband, improve valve resolution and threshold sensitivity, extend valve rangeability, and optimize process operation. We also consider when to move up to model predictive control. Read the full text.
