Finding and fixing process control loop problems that PID tuning cannot correct By Mark Coughran Plant engineers and technicians are frequently asked to tune the controller when a control loop’s ...

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 ...

According to ControlSoft Inc.—a provider of advanced process control, performance monitoring, and process diagnostic tools—about 80% of control loops in plants today are not optimally tuned.

I was nursing a lukewarm vending machine coffee recently when I overheard two fresh-faced engineers complaining about the PID tuning process and coming up with ways to tear down centuries of control ...

In his study of control loop performance, David Ender of Techmation, Inc. found that most PID control loops within the average production facility were operating inefficiently.

Why this article is important: This article introduces overall controller effectiveness (OCE) as a new, intuitive metric for evaluating PID loop performance in process industries. It tells how OCE ...

PID loop control capability (up to 8 loops simultaneously) has been added to the CLICK® Series of stackable, Ethernet-capable micro brick PLCs. AutomationDirect adds PID control functionality to CLICK ...

With 85% of loops operating inefficiently while in closed-loop and 65% of them cited as either poorly tuned or de-tuned to conceal other PID-related problems, the study underscored the need for ...
