What Are PID Controllers? PID control is the most commonly used control algorithm, used extensively in industrial, process, and commercial applications and has been universally accepted as the easiest ...
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 ...
Experience — or at least education — often makes a big difference to having a successful project. For example, if you didn’t think about it much, you might think it is simple to control the ...
We’ve been hiding away in air-conditioned comfort to wait out the hot weather afflicting most of the US right now. Luckily we’re keeping busy with the great links coming into our tips box. [Brett] ...
Proportional-integral-derivative (PID) control is one of the most common types of automatic control used in the power industry. A PID controller continuously ...
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 ...

Ask the Automation Pros: How Can You Ensure the Best Rate of Change in the PID Manipulated Variable?
What is the best strategy to get the best rate of change in the PID for a manipulated variable, or is there a more elegant ...
Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...
