METHOD AND SYSTEM FOR CONTROLLING A PROCESS IN A PLANT

摘要

A METHOD AND SYSTEM ARE DISCLOSED FOR CONTROLLING A PROCESS BY ESTABLISHING A CONTROL FACTOR (308, 310, 312) FOR A PROPORTIONAL-INTEGRAL-DERIVATIVE (PID) CONTROLLER (102) USED TO CONTROL A PARAMETER OF A PROCESS RELATIVE TO A SETPOINT (202). A FEEDBACK SIGNAL REGARDING THE PARAMETER OF THE PROCESS IS RECEIVED VIA A SENSOR OF THE PROCESS AND A FIRST FEEDBACK LOOP. AUTOMATIC ADJUSTING OF THE CONTROL FACTOR OF THE PID CONTROLLER IS BASED ON THE FEEDBACK SIGNAL.
