Abstract
A method for generating a motor drive signal is disclosed, which includes: obtaining a non-resonance frequency sine signal, and inputting the non-resonance frequency sine signal into a first system; processing, by the first system, the non-resonance frequency sine signal to obtain a correction input signal; inputting the correction input signal into a second system, and processing, by the second system, the correction input signal to obtain an output signal in the same mathematical form as the non-resonance frequency sine signal, wherein the first system is an inverse system of the second system; and using the output signal of the second system as the motor drive signal. The present disclosure further provides an apparatus for generating a motor drive signal. The method and apparatus for generating a motor drive signal enable the motor to have a smooth output effect after being excited by the non-resonance frequency sine signal.
