- Abstract
In order to improve the positioning accuracy and reliability of the dynamic positioning system and deal with the problem of state estimation of nonlinear system with Gaussian noise, according to the basic principles and methods of Ensemble Kalman Filter (EnKF), a dynamic positioning filtering method is proposed based on EnKF. Then, the simulation results show that the nonlinear observer based on EnKF can effectively estimate the state of the ship and have certain robustness to the observed outliers. The validity of this method is verified at the end of this article.
