An Intelligent Switching Method of Multi-Resolution Models Oriented for Complex System Co-Simulation

With the development of Cyber-Physical Systems (CPS) technologies, many multi-disciplinary collaboration of complex systems that are difficult to solve in a single field can be addressed by simulation in the cyber world. Co-simulation is a typical solution to collaboration of distributed heterogeneous models for complex system. However, the problem of how to select proper simulation models with multi-resolution remains a technical gap for heterogeneous collaboration, which needs more intelligent simulation support provided in the cyber world. In this paper, an intelligent switching method of multi-resolution heterogeneous models oriented for co-simulation of complex systems is proposed. Timing advancing of models with more than one resolution level of simulation resources are incorporated in this architecture. Simulation resources in the form of plug-in-play function blocks can be scheduled by intelligent decision, which can extend the diversity of simulation tasks. After experiments of typical collaborative simulation of a robotic arm in an automatic cruise application scenario, analysis and results show that the proposed method can switch the multi-level simulation resources and trade off well between simulation efficiency and accuracy effectively.
