The present disclosure relates to the technical field of electronic devices, and discloses a method and an apparatus for controlling motor vibration. The method includes: obtaining an input signal based on an expected motor vibration curve, inputting a digital signal sequence of the input signal to an equalizer, and obtaining an output signal after processing by the equalizer, and inputting the output signal to a motor to control vibration of the motor, where the equalizer is a digital filter constructed based on a damping factor and a resonance frequency .sub.n of the motor, and a preset system sampling frequency f.sub.s, a preset damping factor .sub.d, and a preset cut-off frequency .sub.d. The method and apparatus provided in embodiments of the present disclosure have an advantage that an actual vibration effect of the motor can be consistent with an expected motor vibration curve.

A positioning controller includes a position command signal generating unit that generates a position command signal for moving a mechanical load over a set movement distance D by driving a motor; a drive control unit that executes positioning control on the basis of a detected position signal of the mechanical load and the position command signal; a residual vibration information recording unit that stores a plurality of pieces of residual vibration information; and a position command signal parameter determining unit that determines, on the basis of the allowable positioning error and the plurality of pieces of the residual vibration information, a position command signal parameter for generating the position command signal for which the residual vibration amplitude is smaller than or equal to an allowable positioning error.
