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 singular 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.
