We investigate performance bounds for feedback control of distributed plantswhere the controller can be centralized (i.e. it has access tomeasurements from thewhole plant), but sensors onlymeasure differences between neighboring subsystem outputs. Such ‘‘distributed sensing’’ can be a technological necessity in applications where system size exceeds accuracy requirements by many orders of magni...

We propose a flexible and scalable architecture for a network controller platform used for OpenFlow. The OpenFlow technology was proposed as a means for researchers, network service creators, and others to easily design, test, and virtually deploy their innovative ideas in a large network infrastructure, which will accelerate research activities on Future Internet architectures. The technology ...

In the current research on distributed control of interconnected large-scale dynamical systems an often neglected issue is the desire to ensure privacy of subsystems. This gives motivation for the presented distributed controller design method which requires communication and the exchange of model data only with direct neighbors. Thus, no global system knowledge is required. An important proper...

ÐIn this article, we introduce the concept for a distributed railway control system and present the specification and verification of the main algorithm used for safe distributed control. Our design and verification approach is based on the RAISE method, starting with highly abstract algebraic specifications which are transformed into directly implementable distributed control processes by appl...

Timed CPN model of SMC controller communication subsystem is described. SMC controller operates as central unit in a small distributed control-andmeasurement system from LUMEL Zielona Góra. SMC is programmed in ST language available in CPDev design environment. Implementation of the communication subsystem involves communication tasks created during the design stage and executed by SMC taking i...

Timely dissemination of required state information poses a significant challenge in the design of distributed sensor/actuator network-based control systems. In this paper, distance sensitivity properties inherent in many sensor-actuator network-based control systems are exploited to establish conditions under which information within a bounded locality of each controller closely approximates op...

This paper presents a load sharing heuristic for distributed computing on workstation clusters. The approach is novel in that it combines the use of predicted resource requirements of processes (CPU-time, memory requirements, density of the I/O-stream) and a fuzzy logic controller which makes the placement decision. The heuristic is distributed, i.e. each node runs a copy of the prediction and ...

ne way to construct iritelligent controllers is to use an agent0 centered approach in \which the agents themselves determine the global structure of the controller and the inter-agent cooperation methods. To assess this approach, the design and testing of a distributed intelligent coritroller for a laboratory-scale mine refrigeration plant is discussed. Underlying theoretical concepts are brief...

A distributed and scalable architecture for the control of an autonomous robot is presented in this work. In our proposal a whole robotic agent is divided into sub-agents. Every sub-agent is coded into a very simple neural network, and controls one sensor/actuator element of the robot. Sub-agents learn by evolution how to handle their sensor/actuator and how to cooperate with the rest of sub-ag...
