The focus in this paper is on the YJBK (after Youla, Jabr, Bongiorno and Kucera) parameterization of all stabilizing feedback controllers for a given system. A new formulation of YJBK controller architecture is presented and the relation with the double Bezout equation is described. In the standard formulation, a full order model of the system is required for an implementation of the YJBK controller architecture. Here, implementation of the YJBK parameterization will be based on reduced order model, obtained by e.g. model reduction of the full order models or by using identification methods. The controller architecture based on reduced order models will be analyzed with respect to closed-loop stability.
