Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world that would "make ...

Good building mechanical design requires a firm grasp of the mechanical engineering fundamentals (thermodynamics, psychrometrics, the fan laws, etc.). The same can be said about the BAS design needed ...

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 ...

In my previous article on loop tuning, I discussed the importance of field data collection and the importance of a methodical approach to PID tuning. I introduced the concept of the bump test and how ...
