Within modern Distributed Control Systems and Programmable Logic Controllers, it is much easier to prevent integral windup by either limiting the controller output or by using external reset feedback, which is a means of feeding back the selected output to the integral circuit of all controllers in the selection scheme ...

What is reset windup and how can it be prevented?

The natural way to prevent a reset windup is to determine the maximum value of P gain without overdriving the actuator to saturation, based on the maximum error. ... We are interested in an anti-windup compensator that prevents the error from building up excessively in the integral term of the controller.

What is integrator anti-windup?

Integrator windup is a problem in PID feedback controllers that results in overshoot that would not occur if the system were being controlled only in its linear range. The linear range of a control system can be limited by saturation of the feedback controller output.
