Hardware real time interface technology of HILS based on Modelica

To solve the problem that the Modelica model can not directly control the hardware equipment in the process of Hardware in Loop Simulation (HILS), the unified expression technology of interface control module of hardware board and multi domain simulation model is studied on the basis of Modelica. The interface model library of the hardware board is built by analyzing the visualization model equation expression principle, the correlation between multi domain physical models and hardware equipment is implemented in the same simulation environment, and the direct conversion from offline digital simulation models of Modelica to HILS model is implemented, which provides the technical support for the application of Modelica model in HILS. The method is verified by the HILS results of motor rotation speed control.
