Time-robust discrete control over networked Loosely Time-Triggered Architectures
In this paper we consider Loosely Time-Triggered Architectures (LTTA) as a networked infrastructure for deploying discrete control. LTTA are distributed architectures in which 1/ each computing unit is triggered by its own local clock, 2/ the local clocks are not synchronized, and 3/ communication is by the following principle: each communication link acts as a shared and sustained variable that can be, at will, written by the source node and read by the destination node. The loose communication medium used can cause duplication and/or loss of events, as well as distorsion of the synchronization between events occurring at different nodes of the network. While LTT architectures possess significant advantages, their use for distributed discrete control raises serious difficulties. Together with other authors, the authors of this paper have proposed a comprehensive design methodology ensuring the preservation of semantics, from specification to implementation over LTTA. This techniqu...
