Sensitivity of Torque Control for Seven-phase BLDC Machine with One Opened Phase under Constraints on Voltage and Current
Conférence invitée
Date
2018Résumé
This paper deals with control strategies when a sevenphase axial-flux brushless DC machine operates in one opencircuited phase fault by considering constraints on voltage and current. The constraints are related to the converter and machine design in terms of peak values of non-sinusoidal voltage and current. In addition, the sensitivity of the torque control on parameters of new imposed current references under the base speed and in the flux-weakening region is analyzed. The current references taking into account only first and third harmonics in healthy phases are proposed to ensure the torque optimization while phase currents and voltages are within their limits. The usefulness of the control strategies and the parameter analyses are verified by numerical results.
