摘要：
This paper proposes a new method for position estimation of salient-pole permanent-magnet synchronous motor using the second high-frequency current correlated signal in new coordinates in addition to the conventional high-frequency current correlated signal. In the proposed method, even when a spatially-rotating ellipse-shape high-frequency voltage is injected, the relation between the position error and the estimated position shows a linear correlation in the region of ±π/2. © 2010 The Institute of Electrical Engineers of Japan.
