英文摘要：

A sensorless control strategy of permanent magnet synchronous motor（PMSM） which takes iron loss into account is proposed.Since the iron loss is not reflected in the conventional sensorless,the estimation error grows as the speed increases to high speed range and the stator voltage is easy to be saturation, so a new model including iron loss is reconstructed.The finite element software is used to analyze the iron loss resistor,and its effect on estimation accuracy is also discussed.Then a extended electromotive force observer involving iron loss is established.Meanwhile, the proposed method can extend the speed range.Finally ,the compared results with conventional sensorless method show the feasibility and validity of the proposed strategy.
