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 ...

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.

PID control loops are everywhere, found in flight controllers for drones and the temperature control code for 3D printers. How do you teach PID control loops? [Tim] has a great demonstration for this, ...

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 ...

A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...
