摘要：
In this paper, by establishing a mathematical model of ship dynamic positioning system, and considering the force and torque of environment disturbance such as wind, wave and flow, a piecewise controller was designed after the study of ship steering motion on three degrees of freedom, in order to improve control accuracy. The model of fuzzy controller and piecewise controller were respectively simulated using MATLAB in x axis direction. The results of simulation show that the piecewise control method improves the dynamic and static performance of the system, and the system acquires a better control performance.
