Description

technical field

[0001] The invention relates to a multi-core multi-model parallel distributed real-time simulation system, which belongs to the technical field of engineering system real-time simulation. Background technique

[0002] Engineering systems (including aircraft, missiles, satellites, automobiles, etc.) must undergo a large number of ground tests before the design is finalized. The external environment required for the test usually needs to be simulated in the laboratory through a hardware-in-the-loop simulation system. The real-time simulation system is usually an important part of the hardware-in-the-loop simulation system. The real-time calculation of the digital model of the physical system is realized through the real-time simulation system, and the hardware I / O is cross-linked with the external system to achieve the purpose of the hardware-in-the-loop simulation test.

[0003] As the complexity of the engineering system increases, the complexity and accuracy...
