摘要
滤波和状态估计在动力定位系统中起着非常重要的作用。本文在文献 [1 ]的基础上 ,为船舶动力定位系统设计了一增广非线性状态观测器 ,其稳定性通过李亚普诺夫方法得到了证明。该非线性观测器的性能通过对一动力定位船舶模型的仿真得到了验证。
Filtering and stage estimation play an important role in the ship's dynamic positioning(DP) system.Based on reference a nonlinear augmented observer for DP system of ships has been designed in this paper.And the global stability of observer is proven using Lyapunov methods.The simulation results have successfully demonstrated the performance of designed nonlinear augmented observer.
