A hierarchial model is proposed to describe the performance principles of the adaptive system controlling respiratory mechanics. The decision criterion of the controller is modeled by a two-level minimization criterion, where the inspiratory and expiratory flow patterns are determined on the lower level and the overall pattern of breathing on the higher level. The objective functionals are related to the effectivity of breathing. An extension of the lower level model to include control of the rib cage and abdomen separately is also reported.
