|
Abstract:
扬声器一般用于声场激励，本文对扬声器改造为惯性作动器实现对振动板的主动控制进行了研究。首先分析了扬声器作为惯性作动器的物理模型，随后采用分散式多通道速度负反馈控制策略进行实验，最后采用激光测振仪分析板的振动，结果表明：把扬声器改造为惯性作动器用于振动主动控制中是可行的，振幅最多减少峰值的43.4%。
The loudspeaker is generally used for sound field excitation. In this paper, the loudspeaker was transformed into an inertial actuator to realize the active control of the vibrating plate. Firstly, the physical model of the loudspeaker as an inertial actuator was analyzed, and then the experimental research was carried out by using the decentralized multichannel speed of negative feedback control strategy. Lastly, the plate vibration was analysed by laser vibrometer. The results has shown that it is feasible to transform the loudspeaker into an inertial actuator for active vibration control, and the amplitude can be reduced by 43.4% at most.
