Abstract

A method, system and devices to selectively control modal vibrations in an elastic panel with a number of force actuators distributed throughout the surface of the elastic panel to excite/depress the response of one or more vibrational resonant modes included in a prescribed subset. The force actuators are disposed such that prescribed modal excitation/depression may be realized when the actuators are driven by a common source signal.

Description

technical field [0001] This application claims priority to US Provisional Application Serial No. 62 / 745307, filed October 13, 2018. The entire content of the above application is incorporated herein by reference. [0002] The present application relates to a structural control system in which more than one force actuator is used to excite or suppress structural vibration and / or radiated sound. Background technique [0003] For many years, force actuators have been used to excite / suppress the response of more than one resonant mode of vibration in a structure. Modal excitation / suppression techniques can take many forms. One such form is active vibration control with feedback, in which multiple sensors distributed over the structure are first used to estimate the structure's response to disturbances. The sensor signal is sent to the controller, which interprets the sensor signal and then, in response, sends individual drive signals to more than one force actuator distribute...
