要約(日本語): Permanent magnet synchronous motors (PMSMs) are widely used in industry areas. Direct torque control is attractive for these applications. To realize higher performance torque feedback control, accurate observation of flux linkage is very important. This paper presents a method of flux linkage detection based on sliding mode observer (SMO) for a PMSM system. First, a mathematical model with demagnetization fault is established. Then, a SMO is designed based on a minimum extended flux linkage. The SMO improves the tracking precision of the torque and the flux linkage of permanent magnet. Moreover, torque information can be precisely processed using this method in a real-time fashion. Simulations and experiments show the validity of the method.
