摘要:
首先探讨了3种基于数据信息最大化准则的传统传感器优化布置方法,即有效独立法、有效独立驱动点-残差法及运动能法.其中前2种基于Fisher信息阵最大化,而第3种基于运动能最大化.然后运用结构振动模态和三样条插值模态之间的均方差最小和抗噪性能最好,这两种比较准则来确定最优的传感器设置方法.数值分析表明:这3种传感器优化布置法都是有效的,而有效独立-驱动点残差法的效果最好.
Abstract:
Firstly, three traditional sensor optimization arrangement methods based on the data information maximization criterion are discussed, namely effective independent method, effective independent drive point-residual method and motion energy method. The first two are based on Fisher information array maximization, while the third is based on motion energy maximization. Then, the two comparison criteria are used to determine the optimal sensor setting method by using the minimum mean square deviation between the structural vibration mode and the three-spline interpolation mode and the best noise immunity. Numerical analysis shows that these three sensor optimization arrangement methods are effective, and the effective independent-drive point residual method has the best effect.
