Abstract
A method performed by a controller of an electric motor, including generating control parameters, the step of generating control parameters selected from: inputting a given reference torque (T) and a speed command to a torque generation lookup table (LUT) such that the step of generating the control parameters includes the torque generation lookup table at the given reference torque and the speed command; or utilizing an analytical model that includes one or more analytical equations or one or more functions; inputting the control parameters to a DC-link current ripple, torque ripple, and radial force ripple minimization lookup table; inputting position to the DC-link current ripple, torque ripple, and radial force ripple minimization lookup table; generating a reference current profile from the DC-link current ripple, torque ripple, and radial force ripple minimization lookup table; and inputting the reference current profile to the electric motor. Additional methods are disclosed.
