Abstract:
A system and method for compensating a resolver are disclosed. Briefly described, one embodiment receives at least one output signal from the resolver, the resolver detecting a current position of a rotor coupled to the resolver; determines if the current position of the rotor is detected by a first pole-pair of the resolver or if the current position is detected by a second pole-pair of the resolver; in response to determining that the current position of the rotor is detected by the first pole-pair, synchronizes the output signal from the resolver with a first resolver angle error information; and in response to determining that the current position of the rotor is detected by the second pole-pair, synchronizes the output signal from the resolver with a second resolver angle error information.
