N2 - This paper proposes a sliding mode rotor flux observer (SM-RFO) that can measure the real-time rotor flux linkage to diagnose whether a permanent magnet synchronous motor (PMSM) encounters uniform demagnetization fault. Firstly, based on the electrical property of the PMSM, a flux observer based on the sliding mode variable structure theory is developed, with its stability discussed. Then, the impacts of inductance mismatch on the SM-RFO and the fault detection process are analyzed in theory. And to eliminate the negative impacts of the inductance mismatch issue, the applicable working conditions that can ensure the proposed techniques to be accurate are presented. Finally, simulation results are given to validate the proposed flux linkage observer and the demagnetization fault detection strategy.
