Embodiment Construction
[0081] The present invention will be further described below in conjunction with the embodiment in the accompanying drawings:
[0082] According to the behavior of the system after the first-level fault of the switched reluctance motor system,
[0083] According to the performance of the system after the first-order fault of the switched reluctance motor system, the 17 kinds of first-order faults of the switched reluctance motor system are equivalent to four valid states and one failure state in the Markov space. The 4 effective states are capacitor open circuit, inter-turn short circuit, phase loss, and down tube short circuit survival state, which are respectively represented by A1, A2, A3, and A4, and the failure state is represented by A5, and the first-level fault enters five Markov state transitions The transfer rate is shown in Table 1.
