Abstract :
This paper presents a position-sensorless torque controller for switched reluctance machines (SRMs) based on direct instantaneous torque control (DITC). An indirect position estimation to eliminate the need of the position encoder is developed based on current-flux-linkage method. The current-flux-linkage method has advantages of simplicity and requires less computation time. Therefore, the controller can be implemented with a high control bandwidth. The accuracy of position estimation and effects of estimation errors are studied. The functionality of the developed controller and its performance are investigated and verified by experiments over a wide operating range
