Abstract
In this paper, we propose a sensorless control method for synchronous reluctance motors in which an on-line parameter identification method is used which takes account of magnetic saturation. Since motor parameters, especially inductance parameters, vary widely in synchronous reluctance motors, it is important that parameter variation be grasped in order to ensure precise sensorless control. It is, however, very complicated and difficult to measure these parameters in all driving areas. Therefore, we propose an on-line parameter identification method which does not need prior parameter measurements. Using identified motor parameters, rotor position and velocity are estimated by a proposed estimation system based on an extended EMF model. Sensorless control which adapts to parameter variations can be realized by a combination of parameter identification and position estimation.
