Robust Control of a Structural-Acoustical Coupling System by Using the μ_ (-synthesis) Theory μ(-synthesis)方法在结构&声耦合系统鲁棒控制中的应用
We used acoustical coupling mode to connect the system and the public telephone network. 系统与市话网的连接采用声耦合方式便于推广与应用。
Simulation results for the structural acoustical coupling in enclosed space show that the structure-brone noise can be reduced effectively in assigned frequency band, the maximum control value for noise peak value is near 20 dB ( A). 封闭空间结构振动声耦合反馈力控制仿真结果表明:通过合理选择性能加权函数,噪声可以在指定频带得到良好的控制,最大噪声峰值近20dB(A)。
