Abstract

This technical note presents a new approach to constructive output feedback robust nonlinear controller design based on the use of IQCs and minimax LQG control. The approach involves a class of controllers which include copies of the nonlinearities in the controller. The linear part of the controller is synthesized using minimax LQG control theory which is closely related to H^∞ control theory.
