本文研究了振动主动控制中压电作动器和传感器位置的优化问题。两个修改的优化准则，确保良好的可观性或可控性的结构，并考虑剩余模式，以限制溢出效应。两个优化变量被认为是每个压电器件：其中心的位置和它的方向。遗传算法被用来寻找最优配置。几个模拟简支板。(C)2009爱思唯尔有限公司保留所有权利。
This paper deals with the optimization of piezoelectric actuators and sensors locations for active vibration control. Two modified optimization criteria are used, ensuring good observability or controllability of the structure, and considering residual modes to limit the spillover effect. Two optimization variables are considered for each piezoelectric device: the location of its center and its orientation. Genetic algorithms are used to find the optimal configurations. Several simulations are presented for a simply supported plate. (C) 2009 Elsevier Ltd. All rights reserved.
