英文摘要: According to the Integrated Prognostics and Health Management technology development of the independent power system in the aviation, aiming at the urgent need to address the key issues, namely fault detection, diagnosis and prediction, one targeted fault diagnosis and prediction method based on inverse problem solution, has been proposed in this project, the research contents are as the followings: First to investigate the comprehensive variation law of multi-physical parameters in the key position under the situation of independent power system fault conditions, include the deep coupling relations between them. Then to study the methods of integrated monitoring and handling of these parameters, select and extract the fault characteristics accordingly, to research the state modeling and simulation technology of independent power system. Hereafter, based on these findings, using the inverse problem theory, considering in combination with comprehensive testing of the external multi-physical state parameters of the independent power system information features, to establish one new analytical theory and solution algorithm for the independent power system operating status Fault diagnosis and prediction, meanwhile, to improve the principle of the analytical algorithm and the actual application process using the act
