Abstract:
A resolver to digital converter is provided and includes first and second inputs to receive signals from a resolver and an output to provide an estimated angle of a rotor. The sine component signal is multiplied by the cosine of the estimated angle and the cosine component signal is multiplied by the sine of the estimated angle, and a difference between them is calculated to provide an error measurement. The estimated angle is updated by the error measurement.

Claim (Index 8):
A method of converting resolver signals to an estimated rotor angle, the method comprising:\n receiving a first signal from a resolver, the first signal representing a sine component of a rotor angle; receiving a second signal from the resolver, the second signal representing a cosine component of the rotor angle; multiplying the first signal by a cosine of the estimated rotor angle to provide a third signal; multiplying the second signal by a sine of the estimated rotor angle to provide a fourth signal; determining an error measurement as a difference between the third and fourth signals; and updating the estimated rotor angle by selectively alternating, at least once per rotation of the rotor, between addition and subtraction of the error measurement.
