摘要

设计了磁悬浮支承单元结构,并将其应用于双层隔振系统中。根据该结构和磁悬浮支承与双层隔振的特征,建立了半主动输出反馈的模糊控制器,通过调节磁悬浮支承单元的电流,改变磁力从而获得系统的最佳刚度。仿真分析该半主动控制双层隔振系统与最优被动双层隔振系统在相同复杂信号激励下输出力曲线。另外,还仿真分析了在冲击激励下,系统的输出力曲线。结果表明,半主动输出反馈模糊控制下的磁悬浮支承双层隔振系统的隔振效果与抗冲击特性优于常规最优被动隔振。

Abstract

In this paper, a unit of magnetic suspension supporting is designed and applied to floating raft vibration isolation system. A semi-active output feedback fuzzy controller is designed for floating raft isolation system with magnetic suspension isolator .Then, optimal stiffness of magnetic suspension isolator and the appropriate current could be obtained. Input force and output force response of floating raft isolation system, under complex-frequency exciting signal and impact exciting signal are simulated. The simulation results indicate the performance of magnetic suspension supporting floating raft isolation system with semi-active fuzzy control method is more effective in vibration isolation in comparison with the passive optimal system.
