Fault-Tolerant Coupling of Real-Time Systems: A Case Study

This paper demonstrates the application of a model-based coupling approach to cope with non negligible coupling imperfections and faults of interconnected real-time systems. Performance degradation of the coupled overall system is prevented via model-based prediction schemes, which compensate for effects caused by e.g. deadline violations of the coupled real-time systems or data losses and transmission time delays due to the communication network. As an example, the real-time co-simulation setup of a modular driving simulator demonstrates the practical applicability and effectiveness of the proposed coupling approach.
