- 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.
