Distributed control patterns using device profile for web services

Automation systems are changing from the centriccontrolled approach to a more flexible and autonomous behavior. The contribution to this philosophy comes from several technologies, including service-oriented concepts. This work focus on some open points of enhanced communication and control patterns and presents it in form of a multi-use communication module. For the development of such systems, the SOA4D imple...

Implementation of a holonic control system in a flexible manufacturing system

Answering to the need to have innovative manufacturing control systems tailored to the current economical, technological, and customer trends, where dynamic and volatile environments prevail, adaptive holonic control architecture (ADACOR) aims to increase the agility and reconfigurability of the production system, contributing for the improvement of the enterprise competitiveness when it works in dynamic and vo...

High-Level Petri Nets Control Modules for Service-Oriented Devices: A Case Study

A solution for the control of service-oriented devices based on modular and special adapted High-Level Petri Nets (HLPN) process description of intra- and inter-control activities is presented. Each component of the architecture may be implemented independently and differently. The only requirement is that it should share its functions as services and obey to the protocols of communication and processes. The co...

A holonic approach to dynamic manufacturing scheduling

Manufacturing scheduling is a complex combinatorial problem, particularly in distributed and dynamic environments. This paper presents a holonic approach to manufacturing scheduling, where the scheduling functions are distributed by several entities, combining their calculation power and local optimization capability. In this scheduling and control approach, the objective is to achieve fast and dynamic re-sched...

Service-Oriented Control Architecture for Reconfigurable Production Systems

Evolvable and collaborative production systems are becoming an emergent paradigm towards flexibility and automatic re-configurability. The reconfiguration of those systems requires the existence of distributed and modular control components that interact in order to accomplish control activities. This paper focuses on service-oriented production systems, which behavior is regulated by the coordination of servic...

Service-oriented process control using high-level Petri Nets

Service-oriented systems constitute a suitable approach for the development of modular, flexible and reconfigurable production systems, addressing the current requirements imposed by global markets. This paper focuses on the process control of Service-oriented production systems, whose behavior is regulated by the coordination of services that are available from distributed modular and collaborative control com...

Phase space signal filtering

In this article we propose an approach based on the analysis of phase space of time series, in order to improve the filtering process. In some applications the traditional filtering process can produce results that lead to a insufficient representation of the information contained in the signal. Using phase space we can have a different meaning for noise, its correlation with the signal and a supporting theory ...

ADACOR : a holonic architecture for agile and adaptive manufacturing control

In the last decades significant changes in the manufacturing environment have been noticed: moving from a local economy towards a global economy, with markets asking for products with higher quality at lower costs, highly customised and with short life cycle. In these circumstances, the challenge is to develop manufacturing control systems with intelligence capabilities, fast adaptation to the environment chang...
