Field Weakening Operation Control Strategies of Interior Permanent Magnet Synchronous Motor for Electric Vehicles
The field weakening control strategy of interior permanent magnet synchronous motor for electric vehicles was studied in the paper.A field weakening control method based on gradient descent of voltage limit according to the ellipse and modified current setting were proposed.The field weakening region was determined by the angle between the constant torque direction and the voltage limited ellipse decreasing direction.The direction of voltage limited ellipse decreasing was calculated by using the gradient descent method.The current reference was modified by the field weakening direction and the magnitude of the voltage error according to the field weakening region.A simulink model was also founded by Matlab/Simulink,and the validity of the proposed strategy was proved by the simulation results.
