摘　　要：船舶航向与柴油机推进装置是紧密耦合的,但长期以来对它们的控制是完全独立的。根据线性变参数(LPV)系统设计原理,提出了基于LPV的船舶航向与主机联合控制。建立了以船速等为变参数的船舶航向与主机联合控制的LPV模型,采用LPV多胞设计方法,通过状态反馈对闭环极点进行配置,分别设计具有H∞鲁棒性能的航向与主机LPV控制器,实现二者的联合控制。以5446箱班轮为被控制对象,仿真验证了航向与主机LPV控制器在风浪干扰下联合控制的有效性。Ship steering and main diesel engine propulsion system were coupled, but they were always controlled independently. A new approach was presented to design integrated control of the couple based on the linear parametervarying （LPV） system control theory. The LPV models of ship steering and main engine speed were established depending on ship speed etc as the scheduling parameters. By using the closed system poles assigned via state feedback, the controllers of ship steering and main engine speed that satisfying robust H ∞ performance were designed with the LPV polytopic gain scheduled controller design method. Simulation results on 5446TEU container ship prove that the two LPV controllers have good performances under disturbance.
