Abstract

The invention discloses a distributed acoustic vibration active control system based on a star network. The distributed acoustic vibration active control system is mainly composed of a host and a plurality of controllers, wherein the host is connected with all the controllers through network cables, direct network connection does not exist among the controllers, the whole system is in a star network form, the host is composed of a first network communication module, a control monitoring module, a control parameter selection module and a display module, and the controller is mainly composed ofa second network communication module, a self-adaptive control algorithm module, a signal acquisition module and a signal output and drive module. By adding the host and the communication module, thedistributed sub-control systems are linked through the star network so as to monitor the state of each sub-control system, and the control parameters of each sub-control system are further dynamicallyadjusted, so that on the premise of ensuring the overall stability of the system, the independence of each subsystem in the distributed control is maintained.

Description

technical field [0001] The invention belongs to the field of noise and vibration control, in particular to a distributed sound and vibration active control system based on a star network. Background technique [0002] Rotating and reciprocating machinery are commonly used industrial equipment, and the periodic line-spectrum noise and vibration excited during operation are one of the main components of industrial noise and vibration. How to effectively suppress the above-mentioned line-spectrum noise and vibration has attracted increasing attention. , electric power, shipbuilding and other industries have an important application background. [0003] In practical applications, in order to effectively suppress the overall line spectrum noise and vibration of large structures, it is often necessary to deploy multiple actuators and sensor units to implement multi-channel control. The traditional lumped control method connects all actuators and sensors to the same controller, an...
