摘要

本文设计了一种带有自适应模糊控制器的动态定位系统。控制器采用反步算法作为自适应律,并采用模糊系统逼近扰动和不确定性。证明了所提出的自适应模糊控制器在李雅普诺夫意义上是一致有界的。在仿真中,采用自适应模糊控制器可以使DP船舶更好地适应环境干扰和船舶参数的不确定性。

The dynamic positioning system design based on adaptive fuzzy controller
This paper designs a dynamic positioning (DP) system with adaptive fuzzy controller. The Backstepping algorithm is employed as the adaptive law in the controller and a fuzzy system is used for approximating the disturbances and uncertainties. The proposed adaptive fuzzy controller is proven to be uniform bounded in the sense of Lyapunov. In simulation, the DP vessel will be more adaptive with environmental interference and ship parametric uncertainty by using the adaptive fuzzy controller.
