Proportional-Integral-Derivative (PID) control is the workhorse control algorithm for process manufacturers. When tuned properly, it seeks to move a loop’s process variable (PV) to the setpoint (SP) as quickly as possible without overshoot or instability. But, in some cases, even proper tuning is not enough. External factors such as equipment failures, mechanical performance, or incorrect […]

Pressure regulators play an important role in process operations. Wikipedia describes their operation: A pressure regulator’s primary function is to match the flow of gas through the regulator to the demand for gas placed upon the system. If the load flow decreases, then the regulator flow must decrease also. If the load flow increases, then […]
