Abstract :
This paper deals with a tangential interpolation problem which arises in the Q-parametrization of stabilizing controllers for unstable plants. The authors give a fast, recursive algorithm to compute the so-called generating system that can be used to parametrize all stable rational interpolants. The authors´ method is based on a displacement structure approach
