摘要：Abstract This paper presents a structural approach for analyzing a system's diagnosability and reconfigurability, with application on a PMSM drive system in an electric vehicle. Diagnosability analysis is aimed at finding out whether a fault can be detected and isolated when it occurs. Reconfigurability analysis is conducted in order to access a system's fault tolerance capability by system reconfiguration. This paper formalizes conditions of system reconfigurability through structural analysis to check whether a system is able to maintain performance by system reconfiguration under actuation or sensor faults.
