Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough to control the metal's macroscopic electrical properties. Researchers in ...

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 ...

Having problems with your process controls and electrical instrumentation? The source may be a grounding disturbance known as a ground loop. According to the ANSI/ IEEE Standard Dictionary of ...

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 ...

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 ...
