Control valve selection plays a crucial role in optimizing control loop performance, and engineers must consider factors beyond just cost, leakage class and pressure drop. As explored in a Control ...

Success is less about memorizing formulas and more about understanding process behavior, valves, operators and controller ...

Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

Optimizing power plant control systems can be challenging, but new tools are available to simplify and improve the process. On this episode of The POWER Podcast, Executive Editor Aaron Larson spoke ...

Industrial control systems can be categorized in two types: open-loop and closed-loop systems. The open-loop control system is a continuous control system that provides no feedback from its output.

Closed-loop circulating provides pressure control in many drilling and completion applications for which conventional fluid return systems are inadequate. Flexible and scalable to the task, these ...

In this article, as in industry, advanced process control (APC) refers primarily to multi-variable control. Multivariable control means adjusting multiple single-loop controllers in unison, to meet ...
