| Abstract: |
| A procedure for the design of state feedback controller for seismic-excited structures is presented in this paper.The external exciting—controlled structure—control system was simulated using state space model.Based on the convex optimization technology and variance control theorem,the general expression of linear matrix inequalities (LMIs) for state feedback controller with closed-loop poles and the steady variance responses constrained were deduced,in which the poles and variance response of system were guaranteed to satisfy certain constraints assigned in advance.LMI Toolbox of MATALB was employed for optimizing the state feedback controller.At last,a three-story simple lumped mass shear model was used to demonstrate the effectiveness and superiority of the proposed method. |
