Abstract:
Flux identification fo r senso rless su rface moun ted pe rmanent m ach ine ( SM PM ) dr ive based on stochastic fi-l ter has been proposed. A m ix ed observe r has been em ployed in the process. In o rder to reduce the duty o f calcu lation, slid ing mode obse rver has been used in the system to get the pos ition and speed m essage instead o f position sensor. System model has been estab lished byM atlab71 0. The differences between estim ated value and rea l va lue o f flux, and the va riation of estim ated va lues under d ifferent load torques have been ana ly zed w ith sim ulation.
