| 摘 要： | 在结构的振动主动控制中,采用自感知执行器能减小结构的质量和体积,真正实现同位控制。设计了一种基于时分复用解耦系统的压电自感知执行器,使压电元件在传感时隙内作为测量振动的传感器,在执行时隙内作为控制振动的执行器,在放电时隙内释放积累的驱动电荷。设计了开关时序脉冲用于控制3个时隙的切换。基于LabVIEW软件平台,采用正位置反馈控制算法,将时分复用结构的压电自感知执行器用于悬臂梁1阶模态的振动主动控制,实验结果表明达到了良好的控制效果。

| Abstract: | The self-sensing actuator can be used to decrease structural weight and volume,and to achieve true collocated control in the active structural vibration control.A new piezoelectric self-sensing actuator based on the time-division multiplex de-coupling system has been designed,in which the piezoelectric element served as a sensor to measure vibration in sensing timeslot,and as an actuator to suppress vibration in actuating timeslot,and to release the driving charges in discharge timeslot.The switch sequentia... |
