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。


Abstract

For smart isolated system with distributed parameters, the bidirectional piezoelectric variable friction control device which has the function of isolation and control is designed. This control device can produce control force in two orthogonal directions. Furthermore, this control device has the function of isolation. Then relation equation of control force with input voltage for this control device is presented. According to the conditions of this control device producing control force, the semi-active control algorithm which is applicable to the vibration control of system by this control device is deduced. Finally, one bidirectional piezoelectric variable friction control device is simulated numerically and used to smart isolation system with distributed parameters by the semi-active control algorithm under the sequential optimal modal control algorithm based on full state observers. Simulation results show the control system has the excellent control effect.
