摘要：

在应用遗传算法对单频干扰信号作用下的振动主动控制系统反馈参数进行优化研究的基础上，针对宽频干扰信号，以主动控制频率范围内振动传递率的积分最小为优化目标函数，应用遗传算法对振动主动控制系统反馈参数进行优化计算。优化结果表明，对于常见宽频干扰信号的控制，最好不要将相对加速度、相对速度和相对位移引入反馈信号中。

Abstract:

The feedback parameters of an active vibration control system with harmonic disturbance were optimized by means of genetic algorithm. Aiming at the disturbance over wide frequency area, the integral of the vibration transmissibility in range of

frequency for the active vibration control was used as optimization objective function, and genetic algorithm was used to optimize the feedback parameters of the active vibration control system. The optimized results show that relative acceleration, relative velocity and relative displacement should not be used for the feedback signals in the active vibration control system with the disturbance over wide frequency area.
