先进短距起飞垂直着陆飞机的建模与仿真研究

先进短距起飞垂直着陆(ASTOVL)飞行／推进综合控制技术的实现，需要进行大量的理论研究和仿真计算，以确定最优控制律。通过用全量非线性方程来描述的该类依靠气动舵面和推力矢量融合控制技术的飞机运动状态，建立了六自由度的飞机动力学数学模型。由于没有对刚体飞机数学模型和气动数据进行线性化处理，因而所建模型不仅能较全面地反映STOVL飞机的实际运行特性，而且具有较强的通用性。最后，以某型号STOVL飞机为背景，在MATLAB5．2／Simulink环境下研究和开发了飞行数字传真器，介绍了仿真软件的设计思想和程序架构，并通过数字仿真验证了该仿真器的正确性。

Modeling and Simulation Research on Advanced Short Takeoff and Vertical Landing Aircraft

To realize the flight/propulsion integrated control technology for advanced short takeoff and vertical landing(ASTOVL), large amount of theory research and their simulation computation must be done to design the optimal control law. The flight space states of this kind of aircraft, depending on the syncretic control technology of aerodynamics rudder and thrust vector, are described in the entire quantity non-linear equation, and six-degree- of-freedom mathematical model of the aircraft dynamics is established. Since the aircraft mathematical model with rigid body characteristics and aerodynamics data are not dealt with linearly, the established model not only reflects roundly the practice characteristics of short takeoff and vertical landing(STOVL) aircraft, but also takes on general qualities. At last, based on the background of some type of STOVL aircraft, the flight digital emluator is studied and developed under the environment of MATLAB5.2/Simulink, and the designing ideas and program framework on the simulation software are introduced. As a result, the R&D flight digital emluator is correctly validated by the digital simulation.
