摘要
对一种基于压电陶瓷传感器和驱动器的振动主动控制系统进行研究.采用自制小型电荷放大器替代独立式电荷放大器将振动响应转换成电压信号,研究了相应多输入多输出算法,以柔性悬臂板作为被控对象,进行振动主动控制实验,并对本振动主动控制系统进行了试验验证.
In this paper, an active vibration control system using the piezoelectric ceramics as transducer and actuator is researched. The small charge amplifier self-made translates vibration signal into voltage signal instead of independent charge amplifier. MIMO SFX-LMS algorithm is researched. With flexible cantilever as control subject, the active vibration control experiments are conducted, and the active vibration control system is validated through tests
