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 ...

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 ...

The controller contains the “control algorithm,” or control logic equation. The most common control algorithm is called PID, which stands for Proportional (P)-Integral (I)-Derivative (D). When the ...

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 ...

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 ...
