Abstract: | The aim of the research presented in this paper is to actively control broadband vibration on panel structures using multiple sensors. The broadband vibration profile of a panel structure is estimated by using spatial interpolation functions and vibration measurements from the surface mounted sensors. The control objective is then achieved by deriving 'spatial' error signals whose energy represents the spatially-weighted vibration energy over the structure. An optimal H-2 control design using this spatial control approach is discussed to demonstrate the effectiveness of the broadband spatial control on a panel. Numerical results show that the broadband vibration profile can be spatially controlled, not just by minimising the strength of each vibration mode, but also by controlling the relative strength of each mode. |
