Abstract

The purpose of this paper is to develop an approach to improve the tracking characteristics of a small-scale shaking table, which is used in an active structural control system. Firstly, the active control experimental system is briefly described. Then, a system dynamic model is constructed, which integrates hydraulic actuator system and a three-floor test structure mounted on the shaking table. Due to low natural frequency and small damping, the small-scale shaking table cannot meet the experimental requirements. Thus, three states control algorithm based on pole-assignment principle is applied for extending the acceleration bandwidth and improving system damping. Lastly, the experimental results prove that the new controller is effective.
