The decoupling of the active structural acoustic control based on the theory of radiation modes

WU Jingbiao JIANG Zhe ZHU Lifeng (Institute of the Vibration and Noise,Jiangsu University Zhenjiang 212013)  
With the theory of radiation modes,piezoceramics are used as control actuators in the system of active control of sound radiation.According to the characteristics of the first four radiation mode shapes,four groups of actuators are presented.Theoretical analysis and numerical calculation demonstrate that the four groups of actuators can not only reduce the sound power effectively,but also make the decoupling of the control equations.While controlling of the sound power of the first four radiation modes,these actuators can convert the complicated control system of multiple input/output into several simple and each independent systems of single input/output.
