Abstract:To obtain Permanent Magnet Synchronous Motor(PMSM) higher volumetric power density, increasing rotational speed is an effective Way. The core of PMSM control system is the vector control, the vector control is based on motor position signal, therefore, the position signal redundancy algorithm is the key to the PMSM drive system .The failure of position signal has worse influence in high speed region than low speed region. So more and more people are concerned about the reliable operation of the high speed p… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
