摘　　要：提出一种基于模糊积分预测控制器的船舶动力定位系统控制方法,通过引入积分控制器消除了稳态误差,采用模糊控制算法实现了对不确定系统的控制,利用预测控制解决了船舶动力定位中的约束问题,有效地减少了船舶动力定位系统能量的消耗。仿真结果证明,提出的模糊积分预测控制器在满足动力定位要求的同时,大大提高了推力系统的效率,减少了推力消耗。This paper presents a ship dynamic positioning control method based on the fuzzy integral predictive controller. An integral controller is introduced to eliminate the steady state error, while a fuzzy control is adopted to provide satisfied control for uncertain systems, and a predictive control is used to solve constraint problem in the ship dynamic positioning, which can effectively reduce its energy consumption. The simulation results show that the proposed fuzzy integral predictive controller can meet the dynamic positioning requirements with the improvement of propulsion efficiency and the reduction of thrust consumption.
