智能结构振动控制中压电传感器与执行器位置的拓扑优化

摘要

根据奇异值单元灵敏度提出了压电传感器与执行器位置的优化准则，进而建立了一种压电传感器与执行器位置的拓扑优化方法。最后利用算例说明了本文方法的有效性。%A topological optimal method for the placements of distributed piezoelectric sensors and actuators （S／As） of intelligent structures is presented in the paper． the idea of the present method is that sensor／actuator element sensitivities to the singalar values of controllability and observability matrices are used to identify the best locations of S／As． Two numerical examples， the cantilever beam and the model of solar panels， are given to illustrate the application of the present method．
