While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

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.

Unlike competitive models that must be ordered with functionality factory installed, Red Lion's PAX2C PID controllers offer flexible PID control options for process and temperature applications that ...

Looking back through the history of automation, it’s not difficult to see how most advances are extensions of existing technologies. This can be seen at all levels of automation—from the evolution of ...
