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 ...

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 ...

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 ...

Sometimes it can feel like PID tuning is a cross between engineering, mathematics, and the Dark Arts. There are some definitive engineering and mathematical steps to take when tuning a loop (for the ...

The PID Tuning Translator converts PID tuning from one industrial PID controller to another. It converts PID values from any of more than 490 different industrial PID controllers to the new system.

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

A temperature controller is an instrument that controls temperatures, often without extensive operator involvement. In a temperature controller system, the controller accepts a temperature sensor as ...

The two most common categories of process responses in industrial manufacturing processes are self-regulating and integrating. A self-regulating process response to a step input change is ...

How to define the performance criteria of a digital control feedback system, such as a PID control system. How to define the speed and resolution of the control DAC and the sense ADC by using the ...
