Abstract

The experimental system for active mass damper (AMD) is built. The modeling and analysis of hydraulic power mechanism, with multi-degree-of-freedom resonant load, are achieved. Focusing on the problem that the frequency band of shaking table hydraulic system cannot meet the requirement of experiment, the controller is designed by using three-state feedback and three-state feedforward control methods, which extends the acceleration frequency band of shaking table and improves the stability of system. The effectiveness of controllers is experimentally validated. It is concluded that the system can reach the expected response frequency band and stability margins.
