Computing coprime factorizations of distributed parameter systems using Laguerre series

This paper presents a way to compute approximations to the auxiliary functions associated with the Q-parameterization approach to control system design for distributed parameter systems. The technique is put in a form that can be used to recursively compute the (m+1)^st approximation in terms of the m^th approximation. In addition, the recursive formulation highlights the contribution of the new information thereby allowing the designer to decide if the new information is worth the additional computational effort.
