Abstract: A sliding mode observer (SMO) was designed for the rotor position estimation of the sensorless switched reluctance motors (SR motors). The SMO performance was optimized by three means, which are designing new flux linkage model with high accuracy, developing algorithm for the on-line winding resistance estimation and utilizing algorithm for the SMO chatting reduction. Simulation and experimental results show that the presented SMO is accuracy and robust, which results in an improved rotor position estimation.
