Problems solved by technology

[0003] The mathematical simulation technology of the satellite attitude control system has basically matured, but researchers often need to develop different simulation software for different tasks, and the commonality of the simulation code is insufficient
On the other hand, when performing hardware-in-the-loop simulation, it is necessary to make adaptive modifications to the numerical simulation system, and even need to develop two sets of different simulation software, and the hardware-in-the-loop simulation software system in the full star state has not yet been realized.
In addition, the existing simulation system does not yet support full access verification from scheme design to on-orbit mission implementation, which is not conducive to the rapid interpretation and emergency treatment of satellite on-orbit attitude information

Abstract

The invention discloses a system of satellite attitude control integrated simulation and an implement method. The system comprises a simulation computer and an interface expansion board; simulation application under five working modes of complete mathematical simulation, component-level semi-physical simulation, component-level semi-physical simulation, whole-spacecraft semi-physical simulation, satellite-ground united simulation and in orbit attitude visualization can be realized through the combining connection of the simulation system and tested hardware; the system integrates a number of functions in one set to reduce the repeated simulation software development work to achieve the universality and generalization of the simulation system; the visualization and operability of a simulation process is enhanced; the whole flow comparison simulation analysis from scheme design to in orbit test of the satellite attitude control system is supported.

Description

technical field [0001] The invention relates to a satellite attitude control simulation system, in particular to a satellite attitude control integrated simulation system and a realization method, and belongs to the technical field of satellite attitude control simulation. Background technique [0002] The attitude and orientation of the satellite is one of the most important factors to determine the satellite application, which directly affects the design of the payload of the satellite application and the formulation of the performance index of the satellite application. The attitude control system of the satellite is realized by using classical or modern control theory methods on the basis of attitude dynamics, attitude determination and attitude control modeling. Since the ground does not have the conditions to simulate the actual on-orbit space environment, the use of mathematical simulation and semi-physical simulation to simulate the on-orbit operation status has beco...
