Expert System Of Satellite Power System Fault Diagnosis Based On CLIPS

The regular working of satellite power system plays an important role in the smooth operation of the whole satellite.Among the numerous satellite's subsystems,the probability of failure of satellite power systems is the highest,which requires the satellite power system to h ave higher security.It also puts forward higher demand for fault diagnosis theory and technology of satellite power system.With the development of expert system tools and computer science and technology,it is very important to develop a fault diagnosis ex pert system for satellite power system.First of all,the working principle of satellite power supply system is analyzed.The structure of the power system is determined on the basis of the operating principle,along with the diagnosis rule of power system.A ccording to the satellite power system monitoring and diagnosis of the requirements,the overall structure of the diagnosis expert system is divided into knowledge base management system and diagnostic reasoning system,and each module of the function and realization was elaborated.Determining the function of each sub module,and then realizing the design of sub modules.Then,the inference flow of the CLIPS inference engine is analyzed according to the diagnosis reasoning subsystem,along with hybrid programming by embedding CLIPS into C++.And the interface between satellite power expert system and database is designed.Finally,the correctness and feasibility of the system are verified,and the development of the whole expert system is completed.
