Diagnostics on-Board equipment of spacecrafts on the basis of fuzzy logic

In the present article, within the framework of modern requirements for the autonomy of spacecraft, the need to improve the processes of diagnosing onboard equipment of spacecraft based on the use of finite state machines and fuzzy logic is justified. A mathematical formulation of the problem of diagnosing spacecraft onboard equipment is proposed. A model and algorithm for diagnosing spacecraft onboard equipment based on fuzzy logic have been developed. Simulation modeling of the diagnostic process on the example of the onboard repeater of the communication spacecraft is carried out. The reliability of diagnostics for various fuzzy inference algorithms is calculated.
