The general philosophy behind the design of an anti-windup compensator is: design a linear controller, ignoring the control input non-linearity, and then add anti-windup compensator (AWC) to decrease the adverse effect of the non-linearity. In contrast, this paper attempts to provide a simple solution based on the ideal design paradigm: design such a controller that the controller output does not violate its limitations. The new AWC maintains both level and rate constraints. The design is based on a pole-placement controller structure developed for closed-loop iterative controller refinement.
