Research Abstract

Major results of this project are as follows :
(1) Proposal of a method for improving position estimation accuracy :
To reduce position estimation error to 1/5, only 2-bits increment of A/D converter is enough for current detection, meanwhile it is necessary to increase 10 times of current detection data number. This result was clarified by simulation and experimental tests.
(2) Development of new position estimation algorithm to reduce DC voltage limitation of voltage source inverter :
Only one-phase current injection method was newly developed, in contrast with conventional method that requires two-phase current injection. New one-phase current injection method has merit, which reduce maximum DC voltage in voltage-source inverter.
(3) Expansion of position estimation method to surface permanent magnet PM motor with small saliency ratio :
Position estimation method was expanded, which is applicable to surface permanent magnet PM motor with small saliency ratio. In contrast, conventional method was limited to interior permanent magnet PM motor with large saliency ratio. Since new method is based on magnetic saturation phenomenon, it is possible to estimate absolute rotor position.
