摘　　要：建立了反馈系统的数学模型,研究了在被动隔振系统中加入反馈后系统的动态特性,并分析了位移反馈、速度反馈和加速度反馈对系统隔振效果的影响,最终确定PII2控制模型隔振效果最佳。仿真结果表明,与无反馈隔振系统比较,采用了反馈隔振后的系统其隔振效果有了极大改善。In this paper, the mathematical model for the feedback system is established to study the dynamic characteristic after the passive vibration isolation system added to feedback control, and to analyze the effects of displacement feedback, velocity feedback and acceleration feedback upon the system isolation vibration efficiency. Finally, PII^2 control model is determined to have the best isolation vibration effects. The simulation results indicate that in comparation with isolation vibration system without feed- back, the isolation effect in the system has been greatly improved after the feedback isolation vibration is adopted.
