| Abstract: | An optimal method how to set the position of piezoelectric sensors is presented,that is,the sensitivities of the singular-value are used to determine the optimal position of the sensors.First we analyze the system features with finite element method and discuss the observability of the intelligent structure mode,then give the calculation formula to get the singular-value of the observable array.At last,both the optimized principle and steps to determine the position are put forward,and the applications illu... |
