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.

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 ...

PID loop control capability (up to 8 loops simultaneously) has been added to the CLICK® Series of stackable, Ethernet-capable micro brick PLCs. CLICK PID control is streamlined with only the features ...

Development of analog proportional integral derivative (PID) control loops can now be automated thanks to a new EDA tool from Anadigm. With AnadigmPID, users can build an analog PID control loop ...

Good building mechanical design requires a firm grasp of the mechanical engineering fundamentals (thermodynamics, psychrometrics, the fan laws, etc.). The same can be said about the BAS design needed ...
