摘要
对单向电磁作动器和双向电磁作动器进行了研究,建立了基于电磁作动器的单自由度主动隔振系统动态模型,并给出系统的动力学方程。仿真结果表明,在状态反馈的控制策略下,基于双向电磁作动器的主动隔振系统比基于单向电磁作动器或被动隔振系统的隔振效果要好。
A unidirectional electromagnetic actuator and a bidirectional electromagnetic actuator are investigated, the dynamic model for the single-degree-of-freedom active isolation system with electromagnetic actuator is presented, and the dynamic equation is given. The simulation conducted under state feedback control shows that the performance based on bidirectional electromagnetic actuator is better than that of using unidirectional electromagnetic actuator or passive control.
