摘要/Abstract

摘要： 对电磁式作动器主动振动控制的理论原理及控制策略进行了研究。建立了系统的实验模型,用传递函数分析法导出了系统振动传递率和稳定工作时各种反馈变量增益值的限定范围,并用计算机仿真法详细讨论了系统在各种反馈变量条件下,以及不同增益条件下的主动振动控制性能,结果表明:在低频和宽频激振条件下,采用绝对位移、绝对速度、相对位移组合反馈时,具有较好的减振效果

Abstract: The mechanisms of active vibration control using an electromagnetic actuator are investigated in this paper.The system test model is built.The vibration transmissibility is derived from the model by means of transfer function analysis.To determine the limited gain values of various feedback variables,the stability analysis of the active control system is carried out The vibration-isolation characteristics of the active vibration control system of the single freedom degree are discussed using an electromagnetic actuator for various variables and various feedback gain valnes with computer simulation.It si shown by analysis results that the combined feedback variable method based on absolute position,absolut evelocity and relative position variables has an effective vibration isolation property even in the condition of the low and wide frequencies.

Key words: active vibration control, electromagnetic actuator, transmis-sibility
