In this paper, a method to determine initial conditions for a class of positive real non integer order models is given. The exposed procedure makes use of a positive real approximation-reduction-realization process. An application, to a second generation CRONE control model, illustrates the proposed methodology.
In this paper, a methodology to approximate a class of inÿnite dimensional models by a bond graph model is investigated. This procedure is designed to preserve the passivity of the initial model. Through interconnections of passive elementary blocks (passivity is stable under interconnections), a ÿnite dimensional passive approximate model is constructed.… (More)
