摘　　要：针对直升机结构响应主动振动控制问题,提出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。Aiming at the optimization of sensors＇ number and locations in active control of structural response（ACSR） for helicopter,an optimization selection method was given out.The method can effectively reduce the number of sensors and find their relevant optimization locations,and at the same time the effect of vibration reduction maintains almost the same as before.So the control scale of hardware can be reduced distinctly.The optimization procedure was resolved with the genetic algorithm.Taking the Z11 light helicopter as an example,the effectiveness of the method was validated.The results show that using the optimization method,the best collocation scheme of sensors in ACSR can be achieved,with the fewest sensors and good effect of vibration reduction in all observed locations.
