Torque Cross Compensation Control of Modular Switched Reluctance Motor Systems Under Adaptive Three-switch Conduction Mechanism
The modular converter provides a promising solution towards converter unification and industrial massive production for switched reluctance motor(SRM)applications.To overcome the inherent torque plummet issue caused by the inherent two-phase series excitation and the voltage limitation of the existing modular topologies,an adaptive three-switch conduction-based torque control strategy is proposed in this paper.By establishing a three-step commutation mechanism based on an adaptive interval division principle,a torque cross compensation strategy is proposed.The peak value of the phase current is suppressed and the torque tracking accuracy is improved effectively for the modular SRM drives.Finally,the simulation and experiments are carried out based on a 150 W,three-phase 12/8-pole SRM to verify the feasibility and effectiveness of the proposed scheme.
