奇异值摄动法及其在智能结构振动控制中的应用

Singular Value Perturbation and Its Application in Vibration Control of Intelligent Structures

在可控矩阵奇异值一阶摄动的基础上提出了一种选取智能结构的执行器优化位置的数值方法。利用该方法详细讨论了如何选取智能结构的执行器优化位置及反馈控制对结构动态位移响应的影响 ,最后举例说明了该方法在实际中的应用。

A technique for determining optimal locations for actuators of intelligent structures is presented on the basis of the 1st order singular value perturbations of controllability.With this method the optimal placements of actuators of the intelligent structures can be selected and the impulse response of structures due to different locations of actuators with the same control law is analyzed.A numerical example is given to illustrate the applications of the method.
