Fault-Tolerant Control of PMSM With Inter-Turn Short-Circuit Fault [PDF]
IEEE Transactions on Energy Conversion, 2019 Fault diagnosis and fault tolerant (FT) control of electric drive systems have been extensively studied by many researchers. Naturally, one would like to use fault diagnosis information to improve FT control to achieve good post-fault performance while it is safe to do so.
