结构声辐射有源控制的模态可控性和可观性研究

Modal Controllability and Observability for Active Structural Acoustic Control

指出声辐射的结构有源控制方式 ( ASAC)将突出控制系统的模态可控性和可观性问题 ,此问题的解决与否是 ASAC方式能否实用化的关键。就结构声辐射前馈有源控制的模态可控性和可观性得出了具体判据。有关结论对传感器、致动器布置及控制器设计有重要的指导意义。

This paper shows that for active structural acoustic control the modal controllability and observability become more important since they are the key points to decide if the technology can be put into practice. The paper gives the criteria about the modal controllability and observability for the active structural acoustic feedforward control systems. The results are useful to quide to the distribution of sensors, actuators and the design of controller.
