ABSTRACT:
Anti-windup and noise protection that can be used with any general digital controller. The anti-windup technique allows the implementation of noise filtering techniques to decrease or eliminate chatter of the control output at the limit. In a higher order controller that uses a feedforward signal, the anti-windup technique prevents an unexpected change in the control output when a step change occurs in the feedforward signal. The technique can be used to provide anti-windup protection in both single layer and multi-layer control schemes.
