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 ...

In 2012, Automation World published an article looking at the decision factors faced when choosing electric or pneumatic actuators. More than a decade later, manufacturing engineers and OEMs still ...

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 ...

Continued innovation in modeling and algorithm development has led to new process control for the Cyberbase/SDI drilling command center. Collaboration between the International Research Institute of ...

The research flow loop is used to study how a clean hole can be created during the drilling process. For example, when a well is being built, solid particles, called “cuttings” are generated as rocks ...
