| 摘 要： | 针对实际工程领域中存在的伴有大量宽频干扰/噪声的复杂振动环境,直接影响了常规振动主动控制(AVC)的性能甚至稳定性。本文提出了频域加权的线性二次高斯型(LQG)控制方法,实现对特定振动主频重点衰减的同时,保证宽频域的干扰/噪声控制作用。最后利用压电陶瓷贴片的悬臂梁,振动主动控制试验验证了该方法的有效性。

| Abstract: | Aiming at complex vibration environment characterized by broad frequency band disturbance/noise in practical engineering fields,which directly impairs the performance even stability of an active vibration control(AVC) system,the improved linear quadratic Gaussian(LQG) control method with frequency weighted is presented to realize intensive vibration suppression at dominant vibration frequencies while to assure broad frequency band disturbance/noise attenuation.At last,the effectiveness of the proposed method is verified by a series of AVC experiments on an intelligent beam. |
