Title:
EXCITATION VOLTAGE GENERATION METHOD, APPARATUS AND DEVICE, MEDIUM AND TEST METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/128077
Kind Code:
A1
Abstract:
An excitation voltage generation method, apparatus and device, a medium and a test method and system. The excitation voltage generation method comprises: obtaining vibration amount corresponding to a plurality of preset moments from a preset vibration waveform (S10); obtaining motor parameters corresponding to each preset moment, wherein the motor parameters comprise a quantity of state and nonlinear parameters, and the quantity of state and the nonlinear parameters are obtained by testing a preconfigured motor model (S20); and according to the vibration amount, the quantity of state and the nonlinear parameters, calculating excitation voltage corresponding to each preset moment, wherein the excitation voltage is used for exciting a motor (S30) so as to enable the motor to generate a vibration effect corresponding to the excitation voltage.
