AI Technical Summary

Technical Problem

In coupled simulations, as the number of simulator elements increases, it becomes difficult to analyze velocity and accuracy issues, as FMI and HLA standards lack analysis functions, and existing protocols like DCP can only monitor real-time requirements but not perform further analysis.

Method used

A control system that combines multiple simulators to perform coupled simulations, featuring a wrapper unit for executing simulations and obtaining state variables, a first control unit for managing logical time and instructing simulations, a second control unit for information exchange, and an analysis unit for detecting abnormalities in the simulation.

Benefits of technology

The control system provides an analysis technique for coupled simulations, enabling users to manage and improve the system by automatically collecting and analyzing simulation data, detecting abnormalities, and visualizing results, thus improving productivity and accuracy.

Abstract

Provided is a control system (10) for controlling a co-simulation in which a plurality of simulators are combined to create a single simulation, said control system comprising: a simulator wrapper unit (11) that executes a simulation in the plurality of simulators and that obtains information including a state variable of a calculation process inside each simulator; an execution control unit (12) that, in accordance with causal relationships between the plurality of simulators, performs logical clock management with respect to each simulator and that uses the logical clock to instruct the simulator wrapper unit (11) to execute a simulation in each simulator; a data circulation control unit (13) that, in accordance with the causal relationships between the plurality of simulators, controls information exchange between the simulators, and that acquires cooperation information which is information exchanged between simulators; and an execution management unit (14) that analyzes whether or not there is an anomaly in the co-simulation, on the basis of the cooperation information and the state variables of the calculation processes.
