TLDR
The decentralized stochastic control of a linear dynamic system consisting of several subsystems is considered by the introduction of a coordinator who collects measurements from the local controllers periodically and in return transmits coordinating parameters.About:

Multilayer control of large Markov chains
J.-P. Forestier,Pravin Varaiya +1 more
TL;DR: In this paper, the computational burden associated with controlling a plant modeled as a Markov chain with a large number of states is addressed by proposing a two-layer feedback control structure.

A decentralized computational algorithm for the global Kalman filter
TL;DR: In this article, a new decentralized computational structure is developed for optimal state estimation in large scale linear interconnected dynamical systems, which uses a hierarchical structure to perform successive orthogoilalizations on the measurement subspaces of each sub-system in order to provide the optimal estimate.

Decomposition of dynamic team decision problems
TL;DR: In this paper, the authors consider the question "when can a dynamic team problem be decomposed into several smaller dynamic team problems?" A team is partitioned into several groups of members, and the concepts of independent partition and sequential partition of a team are introduced, which are partitions satisfying some conditions on their precedence relation, nestedness relation and cost function.

On-line hierarchical control for steady-state systems
TL;DR: The basic principles and main properties of hierarchical control structures, which can be applied in steady-state optimization of complex systems, are presented and suitable iterative procedures are proposed and investigated.
Survey of Decentralized Control Methods
TL;DR: An overview of the types of problems that are being considered by control theorists in the area of dynamic large scale systems with emphasis on decentralized control strategies can be found in this paper, where the basic assumptions and mathematical tools associated with the latter are summarized, and recommendations concerning future research are presented.

A Counterexample in Stochastic Optimum Control
TL;DR: In this paper, it was shown that there is no advantage in using non-linear controllers when the objective is to minimize the expectation of a quadratic criterion for a linear system subject to Gaussian noise and with unconstrained control variables.

Team decision theory and information structures in optimal control problems--Part II
Yu-Chi Ho,K'ai-ching Chu +1 more
TL;DR: Equivalence relations in information and in control functions among different systems are developed and aid in the solving of many general problems by relating their solutions to those of the systems with "perfect memory".

Separation of estimation and control for discrete time systems
TL;DR: In this paper, an attempt is made to coordinate the numerous results relating to separation of estimation and control in discrete time stochastic control theory, depending upon the assumptions about linearity, criteria, information pattern, constraints, and noise distributions.
