AI Technical Summary

Technical Problem

Traditional jitter suppression techniques cannot effectively cope with unknown and changing frequencies, making it difficult for the jitter of dual-drive symmetrical guide rails to be automatically adjusted, affecting the synchronous response of the two axes, and key parameters rely on manual setting, which is prone to failure.

Method used

By acquiring the original signal data of the motors on both sides of the dual-drive symmetrical guide rail, converting it into an initial feature vector, using a hybrid network model to identify the jitter type and parameters, and combining the cross-coupling gain coefficient and mode word to adjust the coupling strength of the motor control loop, a target current command is generated to suppress jitter.

Benefits of technology

It achieves precise coordinated motion of dual-drive symmetrical guide rails, effectively suppresses vibration, adapts to changes in mechanical characteristics, and improves system adaptability.

Abstract

This application discloses a jitter suppression method, device, terminal, and medium for a dual-drive symmetrical guide rail. This application relates to the field of data processing technology. The method includes: acquiring raw signal data from the motors on both sides of the dual-drive symmetrical guide rail and converting the raw signal data into an initial feature vector; performing jitter type identification and jitter parameter estimation processing on the dual-drive symmetrical guide rail to obtain a jitter type probability vector and jitter parameters; determining a cross-coupling gain coefficient and a mode word based on the jitter type probability vector, the position synchronization error data corresponding to the motors on both sides, and the current motion stage corresponding to the motors on both sides; and determining the target current command corresponding to the motors on both sides based on the jitter parameters, the cross-coupling gain coefficient, and the mode word. This application aims to achieve precise coordinated motion of the dual-drive symmetrical guide rail while suppressing its jitter.
