Controlling hydraulic motion with precision involves understanding the fundamental difference between servo motors and hydraulic actuators. Electric motors generally respond linearly to control inputs ...

The well-known and nearly hundred years old "proportional-integral- derivative"(PID) controller is a linear feedback control method which adjusts the input signal by ...

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.

After 33 years with Monsanto and Solutia, I can’t help thinking like a user. Even as a contractor, the user view pervades my motivations and goals. I would make a lousy sales and marketing person.

At the core of any modern industrial process is a control system guaranteeing precision, stability, and efficiency. Perhaps the most commonly used are PID (Proportional-Integral-Derivative) ...
