摘要

针对直升机结构响应主动振动控制问题，本文提出了一种传感器优选方法，该方法能够在不减少待减振点数目的前提下，减少传感器数目并优化其位置，且保证系统全局减振效果基本不变，从而有效降低了整个控制系统的控制规模。优化过程采用遗传算法进行求解。以Z11直升机为例对该方法的有效性进行了验证。结果分析表明，利用该优选方法，能够得到传感器数目最少，且全局减振效果降低有限的传感器最优布置方案

Abstract

Aimed at the optimization of sensors’ numbers and locations in helicopter active control of structural response (ACSR), a set of optimization selection method is brought out. This method can effectively reduce numbers of sensors and find their relevant optimization locations, and at the same time the effect of vibration reduction is almost no loss. So the control scale of hardware can be reduced distinctly. The optimization problem is resolved with the genetic algorithm. Taking the Z11 light helicopter as an example, the effectiveness of the method is validated. The results show that using this optimization method, the best collocation scheme of sensors in ACSR can be achieved, with fewest sensors and good effect of vibration reduction in whole observed locations
