Design and Research of Satellite Fault Real-Time Simulation and Verification Platform Based on FMI Standard Model

In order to solve the problem of “new design, many states” and time-consuming on satellite fault verification, the paper proposes a design method of real-time simulation and verification of satellite fault based on FMI standard model. Firstly, based on the model design of the general FMI standard, a set of general satellite model library is built; Secondly, based on FMEA automatic fault management design, the fault classification verification and closed loop management is achieved; Finally, based on the fault injection design of the model, a real-time fault simulation verification platform is built to realize the simulation verification of different types of faults on the satellite system level, at the same time, it has the functions of state monitoring, process control and verification management in the process of fault verification. Through the research in the paper, the satellite comprehensive test can be effectively supported, and the satellite in orbit stable operation can be guaranteed.
