ABSTRACT
Important special classes of interconnected systems are input (BC = 0) and output (CC = 0) decentralized systems, where inputs and outputs are not shared among the subsystems. Input-output decentralized systems are described as
S : x˙ = ADx +BDu+ACx y = CDx,
(26.15)
where both BC and CC are zero. This structural feature helps to a great extent when decentralized controllers and estimators are designed for large plants.
