Abstract EN
Considering the problem of dynamic positioning systems for the slowly varying disturbances, a parametrically adaptive observer is presented.
The peak frequency of observer is adjusted on-line by autoregressive (AR) spectral estimation; other parameters of observer are optimized using particle swarm optimization (PSO).
The peak frequency can be calculated by spectral analysis of the pitch, roll, and heave measurements.
In the spectral estimation, Levinson-Durbin algorithm is used to solve the Yule-Walker equations.
Finally, the computer simulation is given to demonstrate the effectiveness of the proposed method.
