Regenerative braking control method for switched reluctance motor

To solve the problem of large fluctuation of braking current in the regenerative braking control of switched reluctance motor, a regenerative braking control method based on current prediction is proposed. Motor brake are analyzed in the process of the work of the corresponding power switch mode and the method for determining the corresponding state vector, is studied based on the current forecast of switched reluctance motor regenerative braking control of the specific design method, and the effect of simulation verification, and compared with the traditional variable braking phase voltage duty cycle control method compares the simulation analysis, the results show that this control method is compared with the traditional variable braking phase voltage duty cycle control method significantly reduces the motor current braking and braking torque fluctuation degree, thus effectively improve the stability of the braking operation and has good application value.
