Abstract:Due to the complex composition of the ion thruster system, the probability of failure is greatly in⁃
creased. It is very important to carry out the fault diagnosis research of ion thruster through the system simulation
to ensure the normal operation of the ion thruster system. In this paper, the mathematical model of each subsys⁃
tem of the ion electric propulsion system is combined with Matlab/Simulink to realize the simulation model of the
ion thruster system. Based on the data of the LIP-300 ion thruster, the performance of the simulation model is
simulated. The output results of the simulation model are consistent with the existing results in related literature.
Using the system simulation model combined with the fault factors, the ion thruster system in the fault state was
simulated. The fault data obtained and the Matlab neural network toolbox were used to establish the ion thruster
fault diagnosis system. The simulation model was used to generate another set of operating data of the known fault
state corresponding to the fault mode, and the diagnostic ability of the fault diagnosis system was tested by using
