Abstract

The stability problem with current vector control in the deep flux-weakening region is analyzed and a new flux-weakening control scheme to operate the PMSM in the MTPV (Maximum Torque per Volt) region is proposed. The proposed control scheme significantly improves stability and increases speed range while maintaining maximum possible torque capability. The transition between different operation regions in the proposed control scheme proves to be smooth. Simulation and experimental tests are carried out to verify the theoretical analysis.
