Position Control of Hydraulic Servosystem

Position control of the hydraulic servosystem of an uniaxial seismic shake table. The shake table consists of an aluminum mobile platform of 0.9x1.1[m] supported by a set of four linear bearings of high precision and low friction. The hydraulic servo system consists of a double-rod Parker 2H hydraulic cylinder, a high-performance MTS 252.24G-04 servo valve and an MTS 505G2.11 hydraulic power unit and MTS 293.11A-02 accumulators. The position was measured by a Trans-Tek LVDT and the control system was implemented in MATLAB Simulink using a Quanser Q8-USB data acquisition and control card.
