Document Type and Number:
WIPO Patent Application WO/2021/208121
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application is a method for quickly stopping a vibration system, comprising: obtaining an initial vibration waveform to be processed; determining a balancing voltage signal of the initial vibration waveform by using a preset balancing algorithm; capturing, from the balancing voltage signal, a voltage signal starting from a preset position to a destination as a tail end voltage signal; obtaining an output voltage threshold of a target motor, and according to the initial vibration waveform and the preset position, determining a first waveform to be concatenated; according to a system resonant frequency of the target motor, the preset position, and said first waveform, generating a second waveform to be concatenated; and concatenating said first waveform and said second waveform, and driving a vibration system of the target motor by using a target output voltage, so as to quickly stop the vibration system of the target motor at a vibration tail end. The optimization of an initial vibration waveform improves the design efficiency and generation efficiency of a target vibration waveform, thereby facilitating improving the vibration effect of a vibration system of a motor to implement the quick stop function of the motor.
