| Popis: | This paper describes improvement method of position estimation accuracy for signal-injection based sensorless control. Conventional signal-injection based sensorless position estimation methods are based on voltage equation without incorporating mutual inductances between d-axis and q-axis. Therefore as a result, position estimation error is caused by the neglected mutual inductances. In addition, the mutual inductances depend on current, and position. It is difficult to know the actual values of mutual inductances. Therefore, in this paper, improvement method of position estimation accuracy without knowing the cross coupling factor is proposed. The experimental results show the validity of the proposed method. |
