摘　　要：提出考虑船体变形耦合作用的船舶推进系统仿真建模设计方法与系统框架,通过船体变形与动力装置振动烈度间的量化关系体现耦合作用对模型的影响;研究适合推进系统的先进控制技术,通过对简化后的船舶推进系统不确定模型进行仿真试验,结果表明,具有强自适应能力的神经网络控制和模糊控制技术能够满足系统对不确定性及时变非线性控制的要求,具有良好的控制效果。A new approach for modelling the propulsion system coupled with the hull deformation was proposed.The interaction effect of the hull deformation was introdued into the propulsion model via quantifying the relationship between the hull deformation and the vibration intensity of the power devices.Moreover,the control strategies were investigated for the controller design of the marine propulsion system.A simplified propulsion model with uncertainty was established and the performances of different control approaches were discussed.The test results show that the intelligent neural network control and fuzzy control techniques can provide satisfactory performances and are suitable for the control of the marine propulsion system.
