摘要研究表明,超音速巡航导弹爬升段速度变化律与其油耗的大小有着密切的联系,因此本文针对速度控制系统的设计进行了研究。本文中一共设计了三款速度控制系统:忽略发动机动态特性设计的带有比例积分控制器的线性速度控制系统、考虑发动机动态特性设计的带有比例积分微分控制器的线性速度控制系统和用动态逆方法设计的带有比例控制器的非线性速度控制系统,并分别分析了它们的系统品质,仿真结果表明了本文提出的速度控制系统具有良好的工作性能,最后用仿真实例来说明了不同大小的初始速度差对三种控制系统的控制性能的影响,并给出了它们的适用范围。31117 毕业论文关键词 巡航导弹 爬升段 速度控制 发动机动态特性 动态逆
Title A study on velocity control system of the climbing of the supersonic cruise missile
Abstract Studies indicate that the fuel consumption is closely related to the climbing speed variation law of the supersonic cruise missile, so this paper mainly aims at the study of the design of the speed control system .In this paper, a total of three speed control system is designed: the linear speed control system with proportional-integral controller not considering engine dynamics , the linear speed control system with proportional-integral-differential controller considering engine dynamics, the nonlinear speed control system with proportional controller combined with dynamic inverse design method, and analyzed their system quality, simulation results show that the proposed speed control system has good performance. Finally, we will discuss the simulation case with different initial velocity difference between ideal velocity and real velocity and indicate the influence to the performance of three kinds of control system, and their applicable scope is presented.
