AI Technical Summary

Technical Problem

During energy recovery, the thrust fluctuations caused by electromagnetic interference in linear motors affect nanometer-level positioning accuracy, and existing technologies struggle to reconcile the contradiction between energy recovery and high-precision positioning.

Method used

A thrust fluctuation fingerprint database is established. By matching and querying real-time location and vibration data, the current phase and amplitude compensation amount is obtained. Combined with a PID controller, the current parameters are dynamically adjusted to achieve active suppression of thrust fluctuations and phased optimization of the energy recovery process.

Benefits of technology

Maintaining stable electromagnetic thrust during energy recovery avoids positioning deviation and improves the overall control performance and processing reliability of linear motors under complex working conditions.
