In order to design, analyze, or commission a process control system, one must be familiar with the characteristics of the process itself. Although it is highly beneficial for the control engineer to ...

For years, Process manufacturers have used various tools to optimize industrial processes for specific economic objectives. Multi-variable process control (MPC), or better known as Advanced Process ...

Spare a moment’s pity for the process engineer, whose job it is to keep industrial automation running no matter what. These poor souls seem to be forever on call, fielding panicked requests to come to ...

Control loops are said to interact when movement of the final control element of one loop affects not only its own process variable but the process variable of one or more additional control loops as ...

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 ...

PID (proportional, integral, derivative) control has existed for decades and there are many tools available to help implement PID to tune process control systems, thereby making it generally easy to ...

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 ...

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 ...

Systematic methodology is the key to quickly and effectively troubleshooting control circuits. Even the most experienced troubleshooter must rely on a systematic troubleshooting process to solve ...
