ABSTRACT:
A time delay compensated synchronous reference frame controller for a drive motor having a rotor and using an alternating current having a phase angle includes a low pass filter electrically connected to the drive motor for eliminating high frequency components of the alternating current, a coordinate transformer electrically connected to the low pass filter for receiving the alternating current and for defining a moving reference frame based on the phase of the alternating current, a controller electrically connected to the coordinate transformer for driving the alternating current to a proper phase relative to a flux of the rotor of the motor, an inverse coordinate transformer electrically connected to the compensator for receiving the alternating current and for transforming the moving reference frame to a stationary reference frame, and a reference frame shifter operatively connected to this coordinate transformer and the inverse coordinate transformer wherein the reference frame shifter defines a shift in the moving reference frame based on time delays created by the low pass filter and the controller.
