Decentralized adaptive control using partial information

The paper deals with the decentralized adaptive control of the outputs of a discrete-time dynamical systems using multiple controllers, when each controller has only partial information concerning the overall system. While every controller affects all the outputs, each controller has access only to one of the outputs at every instant. Further, it is assumed that the input-output relations describing the system are unknown, and that only partial communication between the various controllers is possible. The paper presents a method for generating the control inputs in a decentralized fashion for asymptotic tracking of desired outputs.
