Active structural control based on LQG/LTR method

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.
