The control of ocean ship is complex. Application of fuzzy controller and PID controller makes the low accuracy and robustness. In this paper, we consider the force and torque of the Marine environment disturbance, study the ship three degrees of freedom movement and put forward piecewise controller and cascade controller applied in the research of ship dynamic positioning system. On the basis of research, we design the ship dynamic positioning system controller. The controller is divided into small-range positioning algorithm stage and remote positioning algorithm stage and different stage take different control strategy. Simulation tests are carried out by use of MATLAB on the effect of the controller of the two stages. Test results show that the paper has characteristics of simple method, fast response speed and high precision. Through the analysis of test results, all the indexes can meet the requirements of ship dynamic positioning.
