Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] Active vibration isolation is to introduce control means into the controlled system, and control the output of the vibration isolation system through a certain control method, so that the force generated by it can offset the vibration of the vibration source, so as to achieve the purpose of vibration isolation.

[0043] At present, the model of the active vibration isolation control method can be found in figure 1 As shown, specifically,...

Abstract

The invention discloses a control method and device for active vibration isolation. The method comprises the steps that vibration signals of a plurality of vibration sources in a vibration environmentare collected, the vibration sources comprise vibration sources with fixed frequencies and vibration sources with non-fixed frequencies, the collected vibration signals on a time domain are convertedinto frequency domain signals, the vibration signals of the vibration sources with the fixed frequencies in the frequency domain signals are determined, the vibration signals of the vibration sourceswith the fixed frequencies are controlled, and the vibration sources with the fixed frequencies are selected from the vibration signals emitted by all the vibration sources and controlled, thereby controlling the vibration signals emitted by the vibration sources with the fixed frequencies and the vibration isolation effect on the vibration signals emitted by the vibration sources with the fixedfrequencies is improved.

Description

technical field [0001] The invention relates to the field of electronic instruments, in particular to an active vibration isolation control method and device. Background technique [0002] Vibration exists in the vast majority of electromechanical systems and can have serious consequences if not properly isolated. For example, in the manufacture of integrated circuits, precision machinery and measuring instruments are very sensitive to vibration. Vibration can shorten the life of mechanical devices and even cause serious damage to the entire system. Therefore, in order to meet the strict and special requirements of the vibration environment in precision machining, measurement and other occasions, efficient vibration isolation control methods are particularly important. [0003] The active vibration isolation control method is a commonly used vibration isolation method, and the vibration signal is usually suppressed in the following manner. Specifically, the vibration sign...
