Motor vibration control method and device and computer readable storage medium

Abstract

The invention provides a motor vibration control method and device and a computer readable storage medium. The method comprises the steps: amplifying a steady-state voltage to generate a first voltagesignal for controlling the accelerated vibration of a motor to a target vibration amplitude lower than the steady-state vibration amplitude; attenuating a starting voltage to the steady-state voltageto generate a second voltage signal for controlling the motor to vibrate from the target vibration amplitude to the steady-state vibration amplitude; generating a steady-state voltage signal used forcontrolling steady-state vibration of the motor based on the steady-state voltage with the preset duration; and finally controlling the motor to vibrate through the target voltage signal generated bythe first voltage signal, the second voltage signal and the steady-state voltage signal. Through the implementation of the invention, the steady-state voltage is amplified to be used as the excitation voltage of the motor vibration acceleration section, and then the excitation voltage is stably reduced to the steady-state voltage, so that the acceleration time of the motor vibration response in the early stage is effectively shortened, and the hysteresis feeling of the motor vibration feedback to a user is reduced.
