Description
Summary:This paper presents a parametrized optimization with constraints mixed with a current searching method to minimize the electric powertrain interior permanent magnet motor torque ripples over the maximum torque-speed curve by injecting the current harmonics. The resulting current harmonics table can thus be used as a look-up table for the motor drive controller to reduce motor torque ripples at different torque-speed operating points.
