【摘要】 鱼雷涡轮动力系统具有许多优于活塞动力系统的结构和工作特性,在现代鱼雷高速度和远航程的战术要求下,大型热动力鱼雷宜采用涡轮发动机作为推进主机。进行鱼雷涡轮动力装置数字仿真是设计涡轮机的重要步骤,为此,该文针对鱼雷涡轮机设计和研制的需求,采用理论分析、经验推导和实验研究相结合的方法建立了鱼雷开式循环部分进气纯冲动式复速级涡轮发动机设计工况及2种常见变工况的数学模型,着重讨论了变工况过程涡轮机的调节控制方案,提出了简便易行的开关喷嘴控制方法,并对其进行了数字仿真研究。涡轮机内部结构及热力学参数仿真结果表明所建数学模型较为准确,变工况控制方法具有正确的理论依据,并易于工程实现。该文的数字仿真方法将为今后更深入的研究提供技术支持。更多还原

【Abstract】 The key for torpedo to implement target pursuit is to design high performance guidance law.Based on equations of relative movements between torpedo and target,some state equations are built and a appropriate evaluation output signal is selected.Then using the H∞ control theory,a nonlinear H∞ guidance law for torpedo and the normal load are obtained by solving Hamilton-Jacobi inequation.Simulation is performed to verify the above research,and the result shows that the guidance law can help torpedo overtake target in a short time with light normal load.So the guidance law is effective for torpedo pursuit with high robustness.Therefore it can be used in design of guidance law for torpedo and anti-torpedo torpedo.更多还原
