A method of controlling an electric vehicle, wherein the electric vehicle comprises an electric motor, a controller, and an inverter, wherein the controller receives a control signal with an instruction to operate the electric motor. In one embodiment, the method includes collecting an operational data set on a plurality of output signals of the inverter and a rotation angle of the electric motor. In one embodiment, the method includes computing a voltage change of the inverter and a magnetic flux of the electric motor based on a predetermined data set and the operational data set. In one embodiment, the method includes adjusting an output of the inverter to offset the voltage change and the magnetic flux, the output being provided to the electric motor to control the electric motor in accordance with the instruction.
