Abstract

A vibration control device comprises a vibration signal processing device and a single-shaft flexible hinge. The anti-vibration device, the first vibration detection device and the second vibration detection device are arranged on the upper plane of the single-shaft flexible hinge. The first vibration detection device and the second vibration detection device are respectively connected with the vibration signal processing device through data lines and are respectively used for detecting an initial vibration signal and a residual vibration signal of the single-shaft flexible hinge; the vibration signal processing device is used for calculating an anti-vibration signal according to the residual vibration signal, calculating an error signal according to the initial vibration signal and the anti-vibration signal, and transmitting the anti-vibration signal to the anti-vibration device; the anti-vibration device is used for generating control force on the single-shaft flexible hinge according to the anti-vibration signal, so that the vibration amplitude of the single-shaft flexible hinge is reduced; and the process is repeated until the error signal is zero, and the vibration control device stops working. An active vibration control mode is provided, and the response speed of the vibration control system is improved.

Description

technical field [0001] The invention relates to the technical field of precision mechanical vibration, in particular to a vibration control device and a control method thereof. Background technique [0002] The vibration of twin-crystal monochromators is a hot issue in the field of synchrotron radiation instruments and equipment. In the past, the stability of monochromators was ensured by passive vibration control. With the improvement of user and experimental requirements, it is difficult for the vibration passive control method to meet the current stability index. Therefore, it is imperative to adopt an active vibration control method for the vibration problem of the twin-crystal monochromator. [0003] Classical algorithms such as adaptive filtering algorithm, neural network, PID, and fuzzy control are widely used in the field of active vibration control. For the vibration control of dual-crystal monochromators, a control system with excellent vibration reduction perfor...
