Title:
TEST METHOD AND DEVICE FOR NONLINEAR PARAMETERS OF MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/258311
Kind Code:
A1
Abstract:
Disclosed are a test method and device for nonlinear parameters of a motor. The method comprises: exciting the vibration of a motor by using an excitation signal; performing synchronous information acquisition on the motor in a vibrating state to obtain a voltage measured value and a current measured value; obtaining a linear parameter initial value and a nonlinear parameter initial value of the motor; obtaining a linear parameter target value of the motor by calculation according to the voltage measured value, the current measured value, and the linear parameter initial value; and obtaining a nonlinear parameter target value of the motor by calculation using adaptive filtering according to the voltage measured value, the current measured value, the linear parameter target value, and the nonlinear parameter initial value. By measuring the nonlinear parameters of the motor, accurate vibration control of the motor is achieved using a nonlinear model, and the control accuracy of the motor is improved, thereby improving the performance of the motor.
