초록 ▼

This invention relates to control systems for the control of noise and vibration. Resonators with adjustable properties are used in conjunction with an electronic control system to change the noise or vibration in a structure. The invention relates particularly to the control of quasi-periodic noise

대표청구항 ▼

A noise or vibration control system for controlling noise or vibration from one or more sources comprising: one or more self adaptive resonator means, attached to one or more points on a structure, whose resonance frequencies are adjustable by control signals; sensor means on said resonator means, the structure, or both said resonator means and said structure that are used to determine tuning of the resonator means; one or more sensor means on the source of vibration, the structure, or both said source of vibration and said structure that can be used to derive frequencies of various components of the vibration; a control system that has as inputs output signal from the sensor means, and as outputs control signals to change the resonance frequencies of the resonator means, wherein the control system incorporates a control algorithm to tune the resonator means close to selected frequencies in the noise or vibration, and to keep them tuned as those frequencies drift or as other factors affecting the resonator means\performances change.
