In this article, an improved torque sharing function (TSF) control using sliding mode control (SMC) is proposed for switched reluctance motor (SRM). First, as for TSF control strategy, due to low increase rate of inductance in the commutation interval, the latter phase is compensated with torque error for torque ripple reduction. Second, SMC is applied in the design of speed controllers and disturbance observers for better comprehensive performance. Regarding speed controller, the novel sliding mode reaching law (RL) is proposed to further suppress the torque ripple and accelerate approaching speed. With respect to the disturbance observer, a modified super-twisting algorithm (STA) is employed to enhance the anti-interference ability. Finally, the simulation and experiments are carried out, which verify that the proposed control method behaves better in aspects of the dynamic response and torque ripple suppression, and anti-interference ability.
