    Abstract
  • This paper introduces linear quadratic Gaussian/loop transfer recovery(LQG/LTR)method into structural control field and investigates active control strategy focusing on the active mass damper(AMD)benchmark model.Firstly,the control model based on LQG/LTR method is established and the model uncertainty is computed using an approximate method.Ideal loop is obtained through introducing velocity feedback.Then,controller is designed according to LQG/LTR control theory,which makes the robust property of linear quadratic regulator(LQR)recover at the input.The simulation results show that the control law is effective and robust.
