Title: METHOD OF PERFORMING QUANTITATIVE ASSESSMENT ON RELIABILITY OF SWITCHING RELUCTANCE MOTOR SYSTEM USING SECOND-ORDER MARKOV MODEL
Abstract:
A method of performing an assessment on reliability of a switching reluctance motor system using a second-order Markov model quantitative analysis comprises: setting, by setting 17 first-order misoperations possibly occurring at the switching reluctance motor system in a normal state to be equivalent to 4 valid states and 1 invalid state in a Markov space, and on a basis of the 4 valid states, system expression forms of second-order misoperations to be equivalent to 14 valid states and 4 invalid states, obtaining, by taking an initial normal state and a final invalid state into consideration, a total number of 19 valid states and 6 invalid states of the second-order misoperations; establishing a valid state transition matrix of the system in the second-order misoperations; computing a sum of all elements in a valid state probability matrix; obtaining a reliability function of the switching reluctance motor system; and computing an average no-misoperation duration of the switching reluctance motor system. Therefore, the embodiment adopts a second-order Markov model quantitative analysis to realize the reliability assessment of the switching reluctance motor system, providing a favorable value in engineering applications.
