摘要

针对带分布参数智能隔震结构,设计出隔震与控制功能于一体的双向滑动压电变摩擦控制装置,该控制装置可以在两个垂直方向滑动产生控制力,同时具有隔震的功能。进一步推导出设置双向滑动压电变摩擦控制装置控制力与输入电压的关系方程。结合双向滑动压电变摩擦控制装置产生控制力的条件,推导出适用于双向滑动压电变摩擦控制装置的半主动控制算法。最后将该控制装置与基于全维状态观测器的序列最优模态控制算法的半主动控制算法结合,用于带分布参数隔震体系的智能控制,仿真结果表明,该控制系统具有良好的控制性能。
For a smart isolated system with distributed parameters,a bidirectional piezoelectric variable friction control device with function of isolation and control was designed.This control device could produce control force in two orthogonal directions.The relation equation of control force with input voltage for this control device was presented.According to the conditions of this control device producing control force,the semi-active control algorithm applicable to the vibration control of the system with this control device was deduced.Finally,one bidirectional piezoelectric variable friction control device was simulated numerically and used for smart isolation of a system with distributed parameters with the semi-active control algorithm and the sequential optimal modal control algorithm based on full state observers.Simulation results showed that the control system has the excellent control effect.
