A Hardware-in-the-loop Simulation System Based on Reflective Memory Real-time Network

The hardware-in-the-loop simulation plays a very important role in prototype design. Both the real-time algorithm and communication are the key techniques in the hardware-in-the-loop simulation. This paper firstly introduces the features of reflective memory real-time network of VMIC. The architectures and functions of the real-time network are described, and the configuration for underwater vehicles control system simulation is presented in details. Finally, the simulation results are given. The results show that this system can enhance the simulation frame time and reduce the influences that exist in the signal transmission process. The hardware-in-the-loop simulation system based on reflective memory is a modular structure. The configuration is flexible, so the system is easy to be expanded, updated and migrated.
