A new design of observer-based compensators for robust asymptotic rejection of persistent disturbances is presented. A systematic method to prevent controller windup caused by input saturation is the observer technique, i.e., driving the observer by the constrained plant input. When using the internal model principle this technique does not stabilize the compensator during saturation. Therefore, several additional measures have been developed to overcome this problem. The approach presented here follows a completely different path. It starts with a compensator of sufficient order, which is first designed for pole placement. By subsequently modifying the feedback of the observer states and, if necessary, of the system outputs, the conditions for a robust disturbance rejection are satisfied. Thus, the observer technique directly assures windup prevention.
