N2 - The purpose of this paper is to develop an approach to improve the tracking characteristics of a small-scale shaking table actuation system, which is used in active structural control system. In this paper, firstly, the active control experimental system is described in detail. Then, the process of constructing analytical model of servo-hydraulic actuation system is presented. The proposed model, in the form of the total shaking table transfer function, accounts for the specific physical characteristics of the small-scale shaking table. Due to low natural frequency and small hydraulic actuator damping, the small-scale shaking table cannot meet the experimental requirement Thus, three states feedback and three state feed-forward control algorithm based on pole-assignment principle is applied for extending the acceleration bandwidth and improving system damping. Lastly, the shaking table experiments are tested and the experimental results indicate that the controller is effective.
