Decentralized stable factors and a parameterization of decentralized controllers
Ranjit A. Date, Joe H. Chow · IEEE Transactions on Automatic Control · 1994
Decentralized stable factors (DSF) are used to extend the stable factorization approach to the design of decentralized controllers. The DSF allow a parameterization of all the stabilizing decentralized controllers in the form of a Youla parameterization. A decentralized controller serves as the central controller, and the Youla parameter has a particular structure and must satisfy an interaction constraint. This parameterization encompasses several other parameterization results on decentralized control systems.>
