摘要
用有效导纳来描述作动器的控制力 ,建立FBRE系统主动隔振模型 ,采用子结构导纳综合法 ,推导FBRE主动隔振模型振动传递的功率流目标函数。在PID等多种控制策略下 ,分别探讨了控制力对结构参数的影响 ,对恰当选择反馈增益参数有指导意义。
A FBRE isolation model is established,and the control force of the actuator is described using Effective Mobility.The power flow transmitted into the foundation that is regarded as the cost function of the active isolation system is derived by subsystem mobility synthesis technique.Under several active control strategies,for example PID,the influence of the control force on the structure parameters are discussed,and this has much guiding significance.
