A system for preventing controller windup in an electric motor includes a limiting module that determines a limited voltage command in response to a commanded voltage exceeding an available voltage of a motor power source, the limited voltage command is applied to an electric motor, a saturation parameter module that determines a saturation parameter based on the limited voltage command, the saturation parameter indicates a magnitude of the commanded voltage exceeding the available voltage, a non-linear processing module that processes the saturation parameter to generate a processed saturation parameter, and a reference current modifier module that generates a modified current command based on the processed saturation parameter, the modified current command is applied to the control system to improve the current command tracking.
