带有UKF滚动时域估计的动力定位控制器
Dynamic positioning controller with UKF moving horizon estimation
摘要
Abstract
A design method for a dynamic positioning ( DP ) nonlinear controller was proposed for surface vessels suffering from random disturbance. This method combined a moving horizon estimation(MHE) based on the un⁃scented Kalman filtering and non⁃switching analytic model predictive control (MPC). MHE based on unscented Kalman filtering was applied to the design of nonlinear filter in accordance with the discrete model, which was transformed by the difference method. UKF was applied to the calculation of the arrival cost. Referring to the dy⁃namic model of a ship, non⁃switching analytic MPC was applied to design DP nonlinear controller of the marine DP . The proposed method was applied to the design of a supply marine DP controller. Simulation results show the effectiveness of the designed DP controller.关键词
