“…Under the action of the servo control link, the shaking table completes the excitation experiment and collects the acceleration signal generated by the current excitation experiment at the same time. The vibration controller uses the corresponding input and output signals and uses the maximum entropy method 0, to obtain and save the frequency response of the system acceleration ring, and updates the new control input signals according to equation (7,8):…”

The hypergravity centrifugal shaking table is widely used in the field of civil engineering, which has the scaling effect and is the most effective means of studying the disaster effect of geotechnical earthquake. The compound control of hypergravity centrifugal shaking table is mainly composed of two parts: position servo control and acceleration vibration control. The position servo control is used to ensure that the shaking table works in a safe working area, and the acceleration vibration control is helpful to further improve the seismic wave reproduction ability of the shaking table. Due to the complexity and diversity of the working conditions of the shaking table, it is proved that under the premise of robust position loop control, the vibration control strategy of the acceleration ring of the hypergravity centrifugal shaking table based on the data-driven idea can effectively improve the vibration control accuracy of the hypergravity centrifugal shaking table. At the same time, the vibration control strategy is only based on the current working state of the shaking table. Therefore, It has stronger adaptive control ability.

Hypergravity centrifugal shaking table is widely used in the field of civil engineering and is considered to be the most effective means to study geotechnical earthquake disaster effect in the world today. Here, the structure of hypergravity centrifugal shaking table system is briefly introduced, and then the necessity and difficulty of the precise control of the position ring of the airborne shaking table in the hypergravity centrifugal shaking table are explained. On this premise, the system modeling and analysis of the unidirectional airborne shaking table with hypergravity are carried out in this paper. A new two-degree-of-freedom controller of the unidirectional airborne shaking table with hypergravity is designed by combining the [Formula: see text] control and an improved internal model control (IIMC) strategy, and the designed two-degree-of-freedom controller is experimentally verified. The experimental results show that compared with the traditional PID control strategy and the single [Formula: see text] control strategy, the two-degree-of-freedom controller designed in this paper can make the position loop control of the unidirectional airborne shaking table with hypergravity have higher control accuracy and anti-interference ability.
