| 中文摘要: |
| 基于声辐射模态的主动控制理论,以固定支承板为例,通过四组作动器在固定支承板上的布放,使其能分别控制不同阶声辐射模态辐射的声功率,来使控制方程解耦,从而设计了比较简单与稳定的单输入/单输出控制系统,模拟计算取得了较好的控制效果。同时本文对控制过程中的溢出等问题进行了一定的探讨。 |
| 英文摘要: |
| Bathed on the theories of Active Structural Acoustic Control and radiation modes, four groups of actuators are equipped on the clamped plate in a certain form,so each group of the actuators can only reduce the sound power radiated by the corresponding radiation mode of the first four modes.Then the control equations can be decoupled,and a simple and stable control system of single input/output is designed.Numerical examples are given to verify the effectiveness of the present method.Finally,the problem of control spillover is discussed. |
