Motor position signal processing method

The invention discloses a motor position signal processing method which includes the following steps: a filtering factor determining step: the filtering factor is calculated according to a cut-off frequency of a low-pass filter and an obtained motor rotor angular frequency; a low-pass filtering step: a preset low-pass filter is adopted to carry out filtering on original position signals of the motor so that post-filtering position signals are obtained; and a linear compensation step: the filtering factor is used to carry out linear compensation on the post-filtering position signals so that post-compensation position signals are obtained. The method is capable of effectively filtering high-frequency jump signals which appear in position signals of a motor and maintaining excellent instantaneity and robustness.
