1. A system for controlling an electric motor that generates an output current from an input voltage command, the system comprising:

  • a first module configured to;

    receive the output current from the electric motor as a feedback, the output current including a direct axis (d-axis) component and a quadrature axis (q-axis) component;

    generate a first voltage command based on an artificial resistance value (Rd, and Rq) and the feedback by using a transfer matrix
