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 ...

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 ...

Proportional-integral-derivative (PID) control is one of the most common types of automatic control used in the power industry. A PID controller continuously ...

Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

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 ...

There is a whole lot to know about servo motors and drivers. You could make a career out of specializing on that one topic. This article is a very small collection of some of the features to consider ...
