摘　　要：针对风翼-柴油机混合动力船舶,建立风翼助航系统的数学模型,并对其控制算法进行分析.基于目标风翼的空气动力特性与风翼回转系统的工作特性,结合实验数据,建立风翼助航系统的数学模型并进行验证.仿真结果表明:对于系统的稳态特性,仿真数值与实际系统的测量值相比误差率小于3%;对于系统的动态特性,仿真结果与实际系统的响应情况吻合;风翼助航系统采用PD控制算法,风翼角度可以稳定精确控制到预期角度,控制误差小于1°,精度可靠.风翼助航系统数学模型能够有效反映实际风翼系统的工作特性,且控制算法能够满足风翼角度控制要求.A mathematical model of the wing-assisted system was proposed for a wing-diesel ship based on the aerodynamic characteristic of the wing,the performance of the wing slewing system and experimental data. The control algorithm of the model was analyzed by using Matlab. Results show that the deviation between simulation and measured value is less than3% for steady-state characteristic of the model. For the dynamic characteristic of the model,the simulation result coincides with measured response of the wing slewing system. The wing＇s angle of the wing-assisted system in the mathematical model is regulated by PD control algorithm,whose control precision is less than 1°. The mathematical model of the wing-assisted system could represent the real performance characteristics. The PD control algorithm can meet the requirements of the wing＇s angle control.
