Abstract

This paper presents an implementation of a position estimation method using a carrier signal injection and a single saliency machine model for permanent magnet (PM) synchronous machines. The method using rotating vector, carrier frequency excitation and heterodyning, tracking observers for position estimation is discussed. The experimental results for the case of a buried PM machine are shown in the paper. It was demonstrated that acceptable results could be obtained from the buried PM machine using the simplest, single saliency-tracking method
