With regard to the high precise three-axis ship motion simulation turntable, the precision is influenced by strong dynamics coupling, such as the moment coupling when three frames rotating at the same time. Therefore, the coupling problem of three-axis ship motion simulation turntable was analyzed profoundly. Then, on the basis of the analysis, in order to restrain the disturbance of coupling torque, the method of dynamic robust compensation based on decoupling control was given. Finally, the compound control strategy including PID control, velocity feedback, position feedback ,input signal differential feedforward and dynamic robust compensation was employed, and a electromechanical Co-simulation of three-axis turntable based on ADAMS and MATLAB was completed. The results of the Co-simulation prove that the method given in this paper can restrain coupling disturbance and improve dynamic tracking performance of three-axis simulation turntable
