Real-time ultra-real-time seamless connection ground rapid simulation test method

Abstract

The invention discloses a real-time and super real-time seamless connection ground rapid-simulation testing method. dSPACE system simulation equipment is used for simultaneously running a real-time simulation testing system and a super real-time simulation testing system, and the real-time simulation and super real-time simulation of critical links and non-critical links in a flight process of a satellite are seamlessly switched according to actual testing conditions to finish on-orbit long-time flight control simulation within a short time, so that the testing integrity, coverage and effectiveness are ensured, the testing efficiency is greatly improved, and the whole simulation testing cycle is shortened.

Description

technical field [0001] The invention relates to a real-time ultra-real-time seamless connection ground rapid simulation test method. Background technique [0002] The test cycle of relative navigation and guidance accompanying flight of high-orbit satellites is long. The whole test process of guidance and accompanying flight lasts for three months, and the test time of each working condition also varies from 4 to 7 days. It is necessary to complete the test and test tasks of the satellite. The particularity of high-orbit satellite missions (relative control of double stars) and the particularity of orbits (stationary orbit), compared with general satellite test missions, not only a test item for the target star control system is added, but the same satellite test items have time Long and complex patterns, if the traditional real-time semi-physical simulation system is used for testing, each complete test will last for 4 months. Considering the requirements of test coverage ...

The particularity of high-orbit satellite missions (relative control of double stars) and the particularity of orbits (stationary orbit), compared with general satellite test missions, not only a test item for the target star control system is added, but the same satellite test items have time Long and complex patterns, if the traditional real-time semi-physical simulation system is used for testing, each complete test will last for 4 months. Considering the requirements of test coverage and parameter deviation, the time constraints of the test will make the The satellite development cycle has become very long, and long-term testing will bring about a huge consumption of manpower, material resources, and time costs

[0003] At present, the rapidity of general satellite ultra-real-time simulation system can reach 1:10, which is only used for pure digital simulation system (the on-board software runs on the virtual simulation platform)
