In most variable-speed drives of PMSM, some type of shaft sensor such as an optical encoder or resolver is connected to the rotor shaft. However, such sensor presents several disadvantages such as drive cost, machine size, reliability and noise immunity. Therefore, the sensorless control of PMSM is desired and various sensorless control strategies have been investigated. This paper presents a novel sensorless control strategy for an interior permanent magnet synchronous motor (IPMSM). A new model of IPMSM using an extended electromotive force (EMF) in the rotating reference frame is utilized in order to estimate both of position and speed. The extended EMF is estimated by the least-order observer, and the estimation position error is directly obtained. The proposed scheme corrects the estimated position and speed so that the estimation position error becomes to be zero. The proposed system is very simple and the design of the controller is easy. Several drive tests are carried out and the experimental results show the effectiveness of the proposed sensorless control system.

This paper presents a sensorless control of IPMSM using an estimated axis error on the basis of an extended emf. In the sensorless control method using a rotational axis model, the approximated model is generally used, thus some problems exist in the sensorless control at IPMSM with a large saliency ratio. In this paper the use of a rotational axis model using an extended emf can accomplish a sensorless control on the basis of an IPMSM model without any approximation. Moreover to confirm the effectiveness of the proposed method this paper shows simulation results of some kinds of drive situations and IPMSMs with various saliency ratios.
