Abstract
Systems and methods are disclosed for determining an operating point for controlling an electric motor. An exemplary system may include a voltage monitor configured to determine a voltage applied to the electric motor. The system may also include a controller configured to determine the operating point based on the voltage. The controller may include a comparator configured to determine a difference between the voltage and a reference voltage. The controller may also include a regulator configured to generate a correction signal for reducing the difference. The controller may be configured to determine the operating point when the difference is below a predetermined threshold.
