Sensorless drive for switched reluctance motor by adaptive hybrid sliding mode observer without chattering

This manuscript presents an adaptive hybrid sliding mode observer for sensor-less SRM drive. Proposed observer consists of two observers; First observer is a current sliding mode observer which estimates phase current and guarantees convergence of estimated currents to real currents. Second observer is a speed and position sliding mode observer which estimates speed and position of SRM using estimated currents. Furthermore undesired effects of chattering are decreased by replacing sign function with a proposed soft adaptive function. This sensor-less SRM drive has been implemented using MATLAB®/Simulink™ environment on the 6/4 poles SRM. The results show that proposed hybrid observer not only estimates currents, speed, and position with high accuracy but also decreases considerably chattering effects.
