摘要
研究了模型预测控制在船舶动力定位系统约束控制中的应用,建立了3自由度动力定位船舶的数学模型,提出了船舶动力定位系统设计中应考虑的各种约束.针对某供应船,根据模型预测控制理论进行了动力定位控制器设计,使约束的处理问题贯穿于控制系统设计的始终.仿真试验验证了模型预测控制算法应用于船舶动力定位约束控制的有效性.
The paper studies the application of model predictive control to restriction control of marine dynamic positioning system and establishes mathematic models of dynamic positioning ships in three degree of freedom. All considerable restrictions in the design of dynamic positioning system are put forward. A dynamic positioning controller is designed based on the theory of model predictive control, which makes the restrictions dealt with all through the design of control systems all along. The simulation experiment demonstrates the effectiveness of the model predictive control arithmetic applied to restriction control of marine dynamic positioning system.
