European researchers are working to create more effective hybrid control systems known as networked embedded systems. Starting in 2004, a European Union-funded project called the Hycon Network of Excellence began “concentrating on the use of advanced automatic control methods to make networked embedded systems fulfill their promise.” The goal was to create hybrid systems in which physical and computational processes mesh to reshape the way health care, transportation, personal spaces, and environmental problems are handled, says project coordinator Francoise Lamnabhi-Lagarrigue. The Hycon team first developed solutions in the area of automatic control and deployed them in real situations for testing. One test involved an automatic refrigeration system for supermarkets, which needed to maintain a steady temperature in the freezers while the external temperature fluctuated throughout the day and night as customers opened and closed the doors and removed products. Other tests were conducted in a solar air-conditioning plant, a sugar-processing plant, a mining and smelting company, and a power station. The Hycon project, which ended in 2009, laid the foundation for the European Embedded Control Institute, which will become a worldwide center for hybrid systems research.
