结构振动声辐射的H控制实验研究

The H control experiment study for structure-acoustic system

  • 摘要: 基于 H控制理论,建立了结构振动声辐射反馈力控制模型,将反馈控制器设计问题转化为标准 H控制问题求解。建立了一套以 TMS320C30数字信号处理芯片为核心的封闭空间弹性壁振动声辐射H控制实验系统。实验取得了在指定频带上噪声最大下降 7 dB的良好效果。

     

    Abstract: Based on the H control theory,the feedback control model of structure-acoustic system is presented in this papers the feedback controller design problem is transformed into the H standard problem to solve.A H control system for enclosed space is also build up,which is based on the TMS320C30 DSP board.In experiment,the noise has been reduced 7 dB (A) in assigned frequency band.
