Switched Reluctance Motor, Torque control, Power electronics
The direct torque and flux control is employed to control the switched reluctance motor drive to minimize the torque ripple. However, the motor draws high current from the source (battery) to develop the required electromagnetic torque during phase commutation, thus reduces the drive efficiency. At the same time, a high ripple (high-frequency components) presents in the source current due to severe energy fluctuations on the motor side, which adversely effects the battery life. To circumvent the above concerns, a new direct torque and flux control scheme is proposed in this paper, which minimizes the source (battery) current ripple and the torque current ripple simultaneously. The feasibility of the proposed control approach is validated through MATLAB simulations under various operating conditions. The simulation results show that the proposed control approach helps to operate the switched reluctance motor drive at the lower switching frequency and also enhances the lifetime of the battery pack in comparison to the existing direct torque and flux control strategies.
