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 controllers offer flexible PID control options for process and temperature applications that require local control across automation processes. For instance, the new Ramp Soak capabilities allow ...

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

A linear control variable yields a uniform surge margin across the full operating range and simplifies both closed-loop and ...

A shift to angular and polar coordinates offers control engineers a more physically rigorous, PID-friendly approach ...
