Abstract

A CAD-design method based on approximate pole placement for a set of models is developed. Dominant poles for all models are simultaneously placed approximately in the least-squares sense. Weighting of the poles allows the constraint of the pole-placement error of dominant poles vis-à-vis nondominant poles. It is demonstrated that a large number of specifications can be taken into account while keeping the complexity of the controller low. The controller obtained gives robust performance in the sense that all specifications are met for all models in the set. A benchmark example is investigated to illustrate the use and the effectiveness of the proposed method.
