“…A solution can be found in [5], in which a method is presented to directly design H ∞ controllers with an observer structure. The approach is to firstly design an observer that bounds the (energy) gain from the disturbances w to the estimation errors by α 1 .…”

This paper considers several practical aspects of designing multi-objective H∞ controllers. As a starting point, the LMI approach for designing multi-objective H∞ controllers, as well as for computing lower bounds on the achievable performance, is summarized. Both techniques are based on the Youla parameterization. Subsequently, two important aspects are to choose the initial observer-based controller used to construct the Youla parameterization and the poles of the Youla parameter itself. In this paper, a specific synthesis technique is suggested for designing H∞ controllers with an observer structure on which to base the Youla parameterization. Furthermore, a heuristic choice of the poles of the Youla parameter is presented. The results are illustrated in an academic example. Finally, the benefits of a multi-objective approach are demonstrated by applying the techniques to a model of a wafer stage; a mechanical positioning system used in IC manufacturing.
