Improve your choice of process control algorithms

摘要

Within the distributed control systems (DCS), commonly used in the hydrocarbon processing industry (HPI), lies a rarely-used version of the proportional-integral-derivative (PID) control algorithm. This algorithm, when properly tuned, can reduce by a factor of four the quantity of off-spec material made during a process upset. As such, it can be the single largest contributor to the benefits captured by improved process control.
