摘要 提出压电分流阻尼技术的虚拟实现方法,用主动控制的方法来真实地模拟被动压电分流阻尼器的效果。利用压电分流阻尼系统的动力学基本方程设计反馈控制器,建立相应于LR串联分支电路的反馈控制结构,整个闭环控制系统稳定或渐进稳定。虚拟实现方法避免了大电感的要求,可以在线调节电感和电阻的数值以适应环境的变化,克服了物理压电分流阻尼器的两大缺陷。数值仿真结果表明,虚拟实现方法能够有效地控制连续结构的振动。 A virtual implementation method is proposed to emulate the effect of passive piezoelectric shunt damping. A controller having a set of second - order dynamic equation and measurement equation is designed and the feedback structure according to the LR series shunt circuit is developed by using the governing equations of piezoelectric shunt damping system, the set of equations does not represent any physical system, the inductor and the resistor only ＂exist＂ as numerical representations inside the controller, the closed -loop control system is stable or asymptotically stable. The virtual implementation method can both eliminate the need for large inductor and adjust circuit component parameters online to adapt to environmental changes, therefore the two disadvantages of the physical piezoelectric shunt damper are overcome, also the feedback gain can be adjusted to implement the a better vibration control effect than the physical piezoelectric shunt damper. The simulation results for a cantilever beam show the effectiveness of the virtual piezoelectric shunt damper for vibration suppression.
