In this paper, a communication complexity view on the problem of decentralized controllability is presented, which uses ideas from information theory and distributed computation. To this end, we present a new approach to revisit a result on the characterization of the necessary and sufficient conditions for the existence of decentralized controllers for stability of linear systems under any cla...

This paper presents computer experiments concerning the decentralized pianola, a hypothetical mechanical music instrument, whose large-scale musical behavior is the result of local physical interactions between simple elements. Traditional mechanical music instruments like the pianola and the music box rely for their operation on the separation between a sequential memory unit and an execution ...

Modern baggage handling processes in airports use destination coded vehicles (DCVs) to transport the luggage at high speeds. These vehicles transport the bags on a “mini” railway network. In order optimize the performance of a DCV-based baggage handling system, the route of each DCV has to be determined. In this paper we consider an event-based model of this system. For routing the DCVs through...

The combination of decentralized and networked control where control loops are closed through a network is defined as Decentralized Networked Control System (DNCS). In this paper, we introduce a general framework that converts a generic decentralized control configuration of non-networked systems to the general setup of Networked Control Systems (NCS). An observer-based decentralized control me...

In this paper, our focus is to compare two decentralized control laws implemented to a three-machine power system which generators are strongly nonlinear interconnected. We present first a linear decentralized control, which gains depend on the system nonlinearity, and confirm, via simulations, its ability to enhance the system transient stability. The second technique is a nonlinear decentrali...

Built on the combined strength of decentralized control and the recently introduced virtual structure approach, a decentralized formation scheme for spacecraft formation flying is presented in this paper. Following a decentralized coordination architecture via the virtual structure approach, decentralized formation control strategies are introduced, which are appropriate when a large number of ...

This paper develops a decentralized leader-follower game for network design of a competitive supply chain problem in which a new chain as the leader enters a market with one existing supply chain as a follower. Both chains produce an identical product, customer demand is inelastic and customer utility function is based on Huff gravity-based model. The leader wants to shape his network and set a...

While training a machine learning model using multiple workers, each of which collects data from their own data sources, it would be most useful when the data collected from different workers can be unique and different. Ironically, recent analysis of decentralized parallel stochastic gradient descent (D-PSGD) relies on the assumption that the data hosted on different workers are not too differ...

This paper presents an explicit solution to decentralized control of a class of spatially invariant systems. The problem of optimal H2 decentralized control for cone causal systems is formulated. Using Parseval’s identity, the optimal H2 decentralized control problem is transformed into an infinite number of model matching problems with a specific structure that can be solved efficiently. In ad...

by Babak Malek, M.S. Washington State University December 2009 Co-Chairs: Ali Saberi and Sandip Roy This dissertation is mainly about discrete-time decentralized control system design. Many largescale systems’ dynamics are characterized by their wide-spread topology and so these systems are considered to be decentralized. Subsequently, analysis of the decentralized systems is generally a really...
