Abstract

The present invention provides a motor parameter testing method, which is characterized in that the method comprises the steps of: providing a motor unit as an optimal motor and at least including a vibrator, the motor unit is arranged on a tooling, and the motor Applying an excitation signal to the monomer generates a displacement of the vibrator; respectively applying N sets of first excitation signals with different voltage values ​​to the motor monomer to obtain N sets of first parameter samples and forming a first sample library, where N is a positive integer And N>1; applying a third excitation signal with a preset voltage value to the motor unit, collecting the measured tooling acceleration of the motor unit; simulating the simulated tooling acceleration of the motor unit according to a plurality of first parameter samples, and The measured tooling acceleration is compared to find the error, and the first sample parameter with the smallest error is selected as the optimal parameter of the motor.

Description

【Technical field】 [0001] The invention relates to the technical field of automatic control, in particular to a method for finding optimal parameters of a motor. 【Background technique】 [0002] With the development and popularization of various consumer electronic devices such as smart phones and smart wearables, people's requirements for tactile experience are also increasing day by day. At present, the main tactile feedback technology is realized by providing rich vibrations through linear motors (LRA), so the vibration performance of the motor has a direct and large impact on the tactile experience. [0003] As the core of the haptic feedback, the linear motor provides a device. Generally speaking, it can be modeled and analyzed more accurately using the classical second-order model, so as to achieve rich haptic effect design. However, the actual motor unit has more or less nonlinearity, which means that the parameters in the classical model are not a constant constant, b...
