This paper proposes a position sensorless control of interior permanent magnet synchronous motors; this method involves the use of an adaptive observer based on direct-type adaptive control for achieving an improvement in responses of speed estimation and control. Although various adaptive observers based on indirect-type adaptive control have been extensively studied so far, improvement in responses of speed estimation and control has not been discussed so much. This paper first shows the response of speed estimation system based on the indirect-type adaptive observer. An adaptive observer based on direct-type adaptive control is then proposed to achieve an improvement in response of speed estimation system. Finally, the effectiveness of the proposed method is proved on some experimental results.
