Analyzing a power system's stability usually begins with a look at the open-loop Bode plot of a buck or flyback converter's power stage. From this plot, the designer extracts phase and gain data for ...
The tuning of proportional-integral-derivative (PID) control loops was an important change at HollyFrontier’s Navajo Refinery in Artesia, N.M. Its hands-on, “mandraulic” culture was no longer cutting ...
Popularity and perceived advantages of current-mode control (CMC) have made it de rigueur as a loop control architecture with many power management IC manufacturers and power supply vendors. Also ...
In this article, as in industry, advanced process control (APC) refers primarily to multi-variable control. Multivariable control means adjusting multiple single-loop controllers in unison, to meet ...
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 ...
It would be a masterpiece of understatement to suggest that control loop compensation holds much significance in power converter design. This is true in part because of increasing demand for ...
TOKYO--(BUSINESS WIRE)--Azbil Corporation (TOKYO:6845) has started sales of the model C1A single loop controller, which features high accuracy and fast response and reduces the burden on personnel, ...
Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...
