Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Power plants–especially coal-fired boilers–pose a set of process control problems unparalleled in other industries. Rapid load ramps, continuous unit demand changes, variable fuel quality and process ...

This is Part 2 of a two-part articles discussing the challenges facing service providers as they transition from TDM-based legacy networks to packet-based networks capable of hosting next-generation ...

On my first project as a combustion control engineer, I was responsible for loop checks and for watching the experts tune the system controls. The first loop I tried to tune solo was the drum level ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

The process controller’s job is to maintain the process variable at setpoint, regardless of whether the setpoint is constant or has just been changed. The controller contains the “control algorithm,” ...
