Abstract :
The paper presents an analytical and experimental evaluation of observer-based methods for estimating the position and speed for switched reluctance motor (SRM) drives. Two observers, the sliding mode observer (SMO) and the standard state observer (SSO), are both found to provide good position and speed estimations. The resolution and reliability of the position estimation scheme are analyzed in detail. Error analysis is carried out under various operating conditions using estimated position and speed in the controller. The results demonstrate the applicability of observer-based sensorless controller for SRM drives
