Learning and Performing Hard Real-Time Skills*

An architecture for hard real-time applications is proposed that enables the user to care safety requirements and time restricted search explicitly. This is supported by an intelligent event-oriented interface to control the technical process. The knowledge-based system “programs” this interface. It stores always safe plans. If the knowledge-based system will eventually find a save and better solution for an existing problem, the program of the interface will be modified. On this architecture a system was implemented that learns skills. Skills are complex compound actions where the temporal and causal coordination of the different actions is important. The system was used to control a hard real-time experiment.
