The control and functional architecture for shop floor control has been studied to manipulate shop floor resources efficiently. In a hierarchical control system, an upper level controller coordinates the activities of a group of lower level controllers in a master – slave manner. Recently, to overcome its various disadvantages, a distributed shop floor control system (SFCS) has been proposed, i...

This paper addresses the distributed H2 and H∞ control problems for multi-agent systems with linear or linearized dynamics. An undirected multigraph with loops is used to represent the communication topology of a multi-agent network. A distributed controller is designed, based on the relative states of neighboring agents and a subset of absolute states of the networked agents. The notions of H∞...

This paper addresses the design of stabilizing controllers for a nested control system where the controller is realized in a distributed manner, considering uncertainty not only in the controller-to-plant and plant-to-controller channels but also in the nest-to-nest, subcontroller-to-subcontroller communication. An input-output approach is taken. Two appropriate controller architectures that st...

In this dissertation, a distributed robust controller, a motion control and sensing architecture, and a terrain feature localization are studied to solve general navigation problems for Compliant Framed wheeled Modular Mobile Robots (CFMMR). This type of wheeled mobile robot uses rigid axles coupled by compliant frame modules to provide both full suspension and enhanced steering capability with...

A reduced-order linear feedback controller is designed and applied to turbulent channel flow for drag reduction. From the linearized two-dimensional Navier–Stokes equations a distributed feedback controller, which produces blowing/suction at the wall based on the measured turbulent streamwise wall-shear stress, is derived using model reduction techniques and linearquadratic-Gaussian/loop-transf...

We consider the problem of controlling distributed storage in a distribution network with renewable distributed generation to minimize network operational cost while satisfying power quality constraints. We assume control is distributed between a global controller (GC) and local controllers (LC) located at the nodes with storage units. Each LC has access to its most recent net load data and run...

In software-defined networking (SDN), a controller program updates the forwarding rules installed on network packet-processing devices in response to events. Such programs are often physically distributed, running on several nodes of the network, and this distributed setting makes programming and debugging especially difficult. Furthermore, bugs in these programs can lead to serious problems su...

In this paper we address the problem of optimizing the Time Window Controller (TW-Controller). This controller was first introduced in 2001 as a supervising mechanism for distributed scheduling of multiclass queuing networks with the objective of stabilizing those networks. It was then also shown that the TW-Controller possesses the ability to improve performance of stable networks. We revise t...
