摘要：
A square-roots Kalman filter nonlinear observer in view of covariance fitting is proposed for the data adaptive problem of square-roots Kalman filter. Based on the Kalman filter, the covariance fitting for square-roots cubature Kalman filter and the square-roots cubature Kalman filter is introduced. In addition, this algorithm is applied to the non-linear observer of ship's dynamic positioning system. The analysis of simulation result prove the validity of the covariance fitting for square-root cubature Kalman filter.
