摘要
使用Simulink对某型飞机燃油系统各部件建立了数学模型。模拟了当一侧油箱故障时的单油箱供油给双发的工作模式。给出了在该模式下油位高度变化等燃油系统关键数据。利用Stateflow模拟了燃油控制系统Central Core System(CCS)的控制功能,并基于MATLAB Real-Time Workshop(RTW)以及VxWorks实时操作系统建立了对此功能的半物理实时仿真系统。完成了对此供油功能的地面闭环测试,为飞机燃油系统建模与控制提供了参考。
The mathematic model of varies components of aircraft fuel system were built using Simulink, and the cross-feed mode, which supplies fuel from one tank to both engines when one of the two main tanks malfunc- tioned was simulated. Certain key data such as fuel height were presented in this mode. Function of Central Core System（CCS） was simulated with Stateflow, and based on MATLAB Real-Time Workshop（RTW） with VxWorks, an outstanding Real-Time Operate System, the Semi-Physical simulation of this function of fuel system is done. Such test has certain reference value for modeling and controlling of aircraft fuel system.
