The active wave compensation driving system was taken as the research object.The active wave compensation electrical control system was designed. And the mathematical model of the driving system was established, transfer function of the system was deduced,and pseudoderivative feedback algorithm was introduced.MATLAB/Simulink was used to do simulation to verify that the pseudoderivative feedback algorithm had good response characteristics, which met the requirement strictly. Finally, the advantages of PDF in the hydraulic servo are highlighted.
