Distributed co-simulation computing based on DDS for large-scale aircraft mechatronic system

Distributed co-simulation is a novel solution for highly integrated large-scale complex system, which can reduce the computing power requirement due to its task decomposition capability. This paper presents a distributed co-simulation computing method based on DDS (Data Distribution Service) for large-scale aircraft mechatronic system. Based on the framework design of the DDS-based distributed simulation computing, the co-simulation middleware and distributed clock synchronization mechanism are proposed to realize the solution process co-operation of distributed models. Finally, a distributed co-simulation system is built to verify the method, and the experiment results show that the models deployed in it can complete the co-simulation task correctly and efficiently.
