Embodiment Construction

[0024] In order to better illustrate the improvement of the present invention to the prior art, before describing the specific implementation of the present invention, the prior art mentioned in the background art section will be described with reference to the accompanying drawings.

[0025] Such as figure 1 Shown is a schematic diagram of a super real-time simulation method in the prior art. Such as figure 1 As shown in , the ultra-real-time simulation of the prior art includes three parts, a dynamics module 11 , a virtual communication module 12 , and a control module 13 . These three modules run on the same computer, and the operating platform of each module is a super real-time platform, and the communication module adopts a software simulation method. Since satellites operate in real time in orbit, and the information exchange between control information and measurement information requires a combination of software and hardware, the communication in the prior art uses...

Abstract

The invention provides a distributed simulation platform based on hardware-in-the-loop and a simulation method. The distributed simulation platform based on hardware-in-the-loop provided by the invention comprises a real-time dynamics platform, a real-time control algorithm platform and a control acceleration platform. When the simulation platform is switched from real-time simulation to super real-time simulation, the control acceleration platform sends an acceleration multiple signal to the real-time dynamics platform and the real-time control algorithm platform; and when the simulation platform is switched from super real-time simulation to real-time simulation, the acceleration multiple signal is 1 or no acceleration multiple signal is sent.

Description

technical field [0001] The invention relates to a super-real-time simulation method based on a hardware-in-the-loop distributed real-time simulation platform, specifically realizing the function of super-real-time simulation on the real-time platform with communication as hardware. Background technique [0002] In the current ultra-real-time simulation technology, it is based on the fact that the simulation platform is ultra-real-time, and the communication modules between the modules are all software simulations, which cannot meet the ultra-real-time simulation requirements of the communication module as hardware. [0003] Most of the aircraft currently operating in the sky have a long mission period, ranging from a day or two to more than a month. During the entire mission cycle of the aircraft, the aircraft does not need to be manipulated most of the time, and the manipulation can only be performed when the satellite is in transit. [0004] If such a long-period task is ...
