Based on high frequency signal injection and IIR filters, a simple method for initial position estimation of Permanent Magnet Synchronous Motor (PMSM) is proposed, based on high frequency signal injection and IIR filters, by use of IIR filters the order can be lowered to 6, which can ensure an easy achievement on a DSP. A simulation model is built to verify this method. Then an offline test have been done to verify the accuracy of estimation.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
