HYPERREAL - A MODULAR CONTROL ARCHITECTURE FOR HRT SYSTEMS

This paper describes the basic ideas of the HyperReal project. It is c entered on the definition of architectural abstractions to design modu lar RT systems. Basic components are reactive agents manipulating data and connectors supporting interactions among agents. Such components are not aware of control strategies, which are managed by a controller . The controller relies on a time-driven model of control, and separat es planning and dispatching of actions. Plans are associated with virt ual clocks that support the explicit management of time. ?The architec tural abstractions allow designers to fully control the temporal behav ior of the system and to reuse components to fit different application -oriented control models.
