Executable Time-Triggered Model (E-TTM) for Real-Time Control Systems

The development of distributed real-time control-systems that must satisfy a certain set of timing constraints with an ever-increasing functionality leads to a considerable complexity growth. Tackling the complexity challenge and providing a consistent notion of time are key challenges, on which this research work is focused. The proposed Executable Time-Triggered Model (E-TTM) provides a deterministic (time and value domain) executable modeling approach for the composable development of distributed real-time control-systems. E-TTM provides a consistent notion of time and supports different strategies to tackle the complexity challenge such as abstraction, partition and segmentation. E-TTM metamodel has been implemented as a C++ library that extends SystemC with the time-triggered Model of Computation (MoC). This approach is illustrated with a case study.
