With system parameters falling into a certain area, the permanent magnet synchronous motor (PMSM) is experiencing chaotic behavior which threatens the secure and stable operation of drive system. To control the undesirable chaos in PMSM, an adaptive dynamic surface control (DSC) law is first designed, which overcomes the problem of “explosion of terms” associated with the traditional backsteppi...

Abstract: In order to solve chattering problem of conventional sliding mode observer (SMO), this paper proposes a exponential reaching law sliding mode observer (ERL-SMO) for a permanent magnet synchronous motor (PMSM) which substitutes exponential reaching law for constant reaching law. The ERL-SMO estimates the rotor position and the angular velocity from the back electromotive force (EMF) ba...
