Satellite attitude and orbit control semi-physical simulation integration method, system and terminal

Abstract

The invention provides a satellite attitude and orbit control semi-physical simulation integration method and system, and the method comprises the steps: constructing a satellite dynamics mathematical model, setting parameters and / or signals needing to be set as faults in the model as global variables, and converting the global variables into a corresponding Rtw format model; compiling and packaging the Rtw format model into a real-time dll dynamic model, deploying the real-time dll dynamic model to an attitude and orbit control dynamic simulation machine, and performing signal interaction with an attitude and orbit control interface simulation module; the attitude and orbit control dynamics simulation machine outputs a dll dynamics model interaction signal, conditions the dll dynamics model interaction signal and then transmits the dll dynamics model interaction signal to the satellite service computer; and the satellite service computer transmits the semaphore of the attitude and orbit control execution mechanism, the semaphore is conditioned and then transmitted to the attitude and orbit control simulation interface module, and satellite attitude and orbit control semi-physical simulation integration is completed. According to the method, the real-time performance, the reliability, the simulation platform cost and other aspects can be greatly improved; on-line modification of all parameters of attitude and orbit control dynamics can be realized, fault parameters can be set, and test coverage is improved.
