ABSTRACT:
Signal compensation apparatus and method compensates for and removes errors due to error factors included in source signals x and y approximated by the sine function and cosine function, respectively, from a measurement apparatus such as a resolver or an encoder. Compensation is achieved by approximating the source signals x and y as expressions which include the terms due to the error factors, detecting the maximum values of x, x+y, etc., and determining coefficients corresponding to the error factors on the basis of the relationships between the maximum values and the coefficients, and removing the errors from the signals provided by the measurement apparatus.
