The tuning of proportional-integral-derivative (PID) control loops was an important change at HollyFrontier’s Navajo Refinery in Artesia, N.M. Its hands-on, “mandraulic” culture was no longer cutting ...
PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...
For example, when migrating from a PLC to a DCS, the PID tuning parameters are converted directly to the proper units and time bases for the algorithm choice. This maintains the established dynamic ...
