Split-ring high precision unbalance vibration control system of magnetic suspension reaction flywheel

Abstract

The present invention relates to a magnetic suspension reaction flywheel open-loop high-accuracy unbalanced vibration control system. It includes the following several portions: displacement sensor, displacement signal interface circuit, rotating speed detection device, magnetic bearing controller, magnetic bearing power amplification drive circuit and flywheel position identification device. The magnetic bearing controller includes axial bearing controller and radial bearing controller, the radial bearing controller is formed from two portions of stabilization controller and unbalanced vibration controller, in which the unbalanced vibration controller can be used for making compensation for displacement feedback of stabilization controller.

AI Technical Summary

Benefits of technology

This patented technology improves on previous methods for controlling unwanted vibrations during operation (such as those associated with turbines). It allows for precise and stable rotation without requiring excessive force or adjustments from other components that may affect its performance. Overall this new technique helps improve efficiency and reduce costs while maintaining good quality products.

Problems solved by technology

This patents discusses different ways to improve the performance of maglev thrusters without causing any unwanted movements during operation. One way involves reducing the influence from external forces like gravity weight fluctuations, called shaft tension variations. Another approach includes adding dampening elements between the rotating part's support ring and the stationary body frame, eliminating interference motions altogether. These techniques aim to achieve better balance behavior and reduced vibrational noise levels under certain conditions.
