Abstract :
The control system of 3 axis, 6 degree-of-freedom (DOF) hydraulic shaking table with 8 actuators is presented to reproduce the multiple DOF reference waveforms. The servo control is used to expand the acceleration frequency bandwidth and transform signals between the 8 actuators and 6 DOF. The multi input multi output (MIMO) vbiration control is presented to update the drive signals and reproduce the reference waveform in high precision. The MIMO waveform replication control test results on one hydraulic shaking table demonstrate the effectiveness of the proposed algorithm.
