CHAT - Control of Heterogeneus Automation Systems
Researchers: Pontus Giselsson, Erik Johannesson, Mikael Lindberg, José Maestre, Karl Mårtensson, Anders Rantzer, Karl-Erik Årzén in collaboration with project partners from University of Pisa, Siemens AG, University of Trento, University College London, Elsag Datamat, Sofidel and University of Salento .
Duration: September 2008 – August 2011
Funding: EU/IST/FP7
Scalability, reconfigurability, and security are three aspects of paramount importance in developing efficient, predictable, and safe control architectures for large-scale networked industrial automation. At present, the state of control systems technology is such that the supervision and control of larger and more complex plants cannot be achieved without considerable costs in terms of hard infrastructure and software development.
CHAT is a research project exploring the research and engineering challenges inherent in the development of algorithms, protocols and procedures for next generation distributed control systems, in order to drastically reducing infrastructure, maintenance and reconfiguration costs.
Involvement
The Department of Automatic Control is involved in developing price mechanisms for distributed control as well as consensus and distributed estimation algorithms. Currently the focus is on using such methods for mobile robot task allocation. We have also provided simulation environments, extended to incorporate industrial network standards to our partners (FlexRay and PROFINET in Truetime).Publications
