Abstract
A resolver signal processing device includes a deviation calculation unit, a PI operation unit, and an integration operation unit. The deviation calculation unit calculates a deviation between a first product obtained by multiplying a signal of phase A by a cosine value based on a reference phase θref and a second product obtained by multiplying a signal of phase B by a sine value based on the reference phase θref. The PI operation unit carries out a proportional integration operation which includes a first integration operation and is defined to converge the deviation on zero on the basis of the deviation. The integration operation unit carries out a second integration operation of integrating a value generated from a result of the proportional integration operation and outputs a result of the second integration operation as phase information of the resolver.
