SWITCHED RELUCTANCE MOTOR SENSORLESS DRIVE WITH ENERGY OPTIMIZING CONTROL STRATEGY

Based on the simplified flux method, this paper presents a position sensorless technique for the switchedreluctance drives (SRD) with energy optimizing control strategy. The method employs a calibration routine to learn themagnetization characteristics of each motor phase at its aligned position. From this information, flux-current characteristics at commutation angle can be approximated through an on-line optimizing process to minimize the energy consumption.Commutation is accomplished by estimating the flux-linked in an active phase and comparing the flux optimized for the commutation angle. The experimental results show that this SRD position sensorless method which is based on an on-line adjustment of commutation angle can be implemented simply and tuned up to achieve high efficiency at wide operation range.
