Control of switched reluctance motor by current profiling under normal and open phase operating condition

This study is focused on a new approach of current profile computation to minimise switched reluctance motor (SRM) torque ripple both in healthy and one open phase fault condition. The analysis of static parameters by means of finite element method is carried out and it is verified by measurements. The mathematical model of SRM is described to simulate all transients. The new current profiling method is applied and tested for normal and faulty operation of a real SRM. The torque ripple is measured at a 10 kHz switching frequency. Lower torque ripple is obtained when compared with standard control methods, both under normal and open phase conditions. The simulations of diverse dynamic states are carried out and compared with experimental results.
