METHOD AND APPARATUS FOR MEASURING PARAMETERS OF MOTOR MODEL, ELECTRONIC DEVICE, AND MEDIUM

WIPO Patent Application WO/2022/134237

A1

A method and apparatus for measuring parameters of a motor model, an electronic device, and a medium. The method comprises: obtaining a voltage signal and a current signal of a motor in a working state, a vibrator of the motor vibrating in two directions (101); obtaining a preset frequency spectrum impedance expression of a motor model, the frequency spectrum impedance expression being determined according to the mapping relationship between kinetic parameters of the motor in the two directions and the mapping relationship between the voltage and current of the motor (102); respectively substituting the voltage signal and the current signal into the frequency spectrum impedance expression to calculate and obtain a plurality of frequency spectrum impedance values of the motor (103); and according to the plurality of frequency spectrum impedance values of the motor, performing fitting calculation on the frequency spectrum impedance values of the motor by using a method of least squares to obtain target frequency spectrum impedance parameters of the motor model (104).
