چکیده
|
This paper deals with a method of phase current sensor fault reconstruction for permanent magnet synchronous motor (pmsm) drives. a new state variable is introduced so that an augmented system can be constructed to treat pmsm sensor faults as actuator faults. this method uses the pmsm two-phase stationary reference frame fault model and a sliding mode variable structure observer to reconstruct fault signals. a logic algorithm is built to isolate and identify the faulty sensor for a stator phase current fault after reconstructing the two-phase stationary reference frame fault signals,which allows the phase fault signals to be reconstructed. simulation results are presented to illustrate the functionality of the theoretical developments. © 2016 changfan zhang et al.
