摘要
建立了超燃冲压发动机的一维稳态模型。特别是对于三模态燃烧,引入一维气体动力学控制方程来描述流动的轴向分布。在稳态模型的基础上,推导出考虑体积效应的一维动态模型。模型运行结果表明,模型结果与实验数据吻合较好。最后,设计了三输入一输出比例积分(Proportional-integral,PI)控制器。仿真结果表明,该模型能够满足超燃冲压发动机控制系统设计的要求。
First,a one-dimensional steady model of the scramjet is established.Particularly for the combustion with three modes,the one-dimensional gas dynamic governing equations are introduced to describe the axial distribution of the flow.Second,a one-dimensional dynamic model is derived by considering the volume effect based on the steady model.The model running results show that the results of the model are in good agreement with the experimental data.Further,a three-input-one-output proportional-integral(PI)controller is designed.The simulations show that the model can meet the requirements of scramjet control system design.
