Research on Optimal control of Switched Reluctance Motor

In view of the low efficiency of switched reluctance motor, this paper first uses the positioning magnetic ring and Hall element to detect the rotor position of the motor. Then, the rotor rotation angle is obtained according to the Hall element state transformation and control the turn-on angle and turn-off angle according to the motor interruption times of the Hall element state conversion cycle. Based on this, the low speed closed-loop control based on current distribution function and variable Angle Position Control and Pulse Width Modulation Control at high speed. Finally, the experiments prove that the strategy can meet the actual operation needs of the motor and realize the accurate calculation of turn-on and turn-off angle and improve the actual operation efficiency of the system.
