摘    要:以某无尾飞翼式高空长航时无人机为研究对象,分析了自然飞机在高空巡航状态时的纵向稳定性,介绍并改进了传统的无人机巡航状态纵向控制律设计方法。通过在Matlab/Simulink中建立仿真模型,对两种方法进行对比分析。分析结果表明,由于无人机飞控系统的自动驾驶仪是始终在环的,不必像传统方法一样考虑带有增稳的控制系统的稳定性。因此,改进的设计方法更适合于无尾飞翼式高空长航时无人机巡航状态的纵向飞行控制系统的设计。

关 键 词:无尾飞翼  高空长航时  无人机  纵向控制律  仿真

Abstract:Focusing on a certain type of high altitude long endurance(HALE) tailless flying-wing unmanned aerial vehicles(UAV),the longitudinal stability of the nature unmanned aerial vehicles is studied in cruise of high altitude, introduced and improved the traditional method of longitudinal control laws. Matlab/simulink is used to establish the simulation model, the differences between two methods are analysed. The analysis result proves that the design for improvement is more suitable for the design of longitudinal control laws for HALE tailless flying-wing UAV because the autopilot of flight control system is always in-the-loop, it is not necessary to consider the stability augmentation performance of control system such as traditional method.
Keywords:tailless flying-wing HALE UAV longitudinal control laws simulation
