Abstract

Electro-hydraulic shaking table (EHST) is a useful experimental apparatus to real-time replicate the desired acceleration vibration signal for evaluating the performance of the tested specimen structural systems. A three axis six degree-of-freedom (DOF) EHST system with eight hydraulic actuators is presented in the paper. A decouple control method is employed to lower the acceleration couple among the six DOF. The procedure of the decouple controller is programmed in MATLAB/Simulink, and then compiled to a real-time PC with Microsoft Visual Studio.NET for implementation. The experimental results demonstrate that a better tracking performance with the improved servo controller is achieved in experiments by using actual EHST.
