Abstract :
This paper presents a sensorless technique for a switched reluctance drive system. By measuring the induced voltage, the shaft position of the rotor position has been estimated. The adjustable speed range of the proposed drive system can vary from 30 r/min to 1500 r/min. The process by which a 32-bit microprocessor system is used to execute the position and speed estimation, speed-loop control, and current-commands generation is shown. Several experimental results validate the theoretical analysis. This paper presents a new direction in the design and implementation of a sensorless switched reluctance drive system
