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 ...

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 ...

This workshop provides instrumentation, automation and process engineers and technicians with the basic theoretical and practical understanding of regulatory control systems and how this can be ...

There are two types of motion control engineers: Those who are comfortable tuning a servo loop, and those who aren't. The latter basically, have two options. The first is to use a non-servo device ...

With the ever-increasing complexity of today’s printed circuit boards, the many voltages required to properly power all the integrated circuit loads are now managed by a range of point of load (POL) ...

Some operational amplifiers (op amps) have an inductive open-loop output impedance, which can be more complex to stabilize than op amps with resistive output impedances. One of the most common ...
