An Acceleration Control Method with Three Variable Controller

Electrical driven shaking tables possess the merits of being clean and easy to install. In order to implement acceleration replication control of the electrical driven shaking tables, a simplified model of the electrical driven mechanicals was established. A three variable controller was adopted both in the Matlab/Simulink environment and the physical system to carry out simulation and experimental study. The simulation and experimental results show that, the three variable controller can expand the bandwidth of the acceleration response of the electrical driven shaking table. Finally, acceleration road spectrum replication experiments were carried out with TVC and realized higher-precision acceleration road spectrum replication control.
