大多数反馈系统都会出现时间延迟，这对有地面驾驶员和控制员的遥控飞行器特别重要。美国宇航局的飞行动力学和控制研究的试验设施，使用缩尺飞行器，机载缩尺运输机研究设施，已开发出远程驾驶的通用运输模型。对这一数值模型的分析以前已经提供了对开环扰动动力学和飞行控制器的影响的深入了解。然而，迄今为止，研究还没有考虑时滞对系统稳定性的影响。目前在机载缩尺运输机研究设施的发展，旨在测试一个缩尺通用客机模型在失控条件下，在延长的距离和高度相比，通用运输模型。在开发此类遥控飞行器的控制器时，了解通信链路和协议中延迟的影响很有帮助。本文利用分支理论和...
Time delays arise in most feedback systems and have specific relevance for remotely piloted vehicles with ground-based pilots and controllers. NASA’s test facility for flight dynamics and control research using subscale vehicles, the Airborne Subscale Transport Aircraft Research facility, has developed the remotely piloted generic transport model. Analysis of a numerical model of this has previously provided insight into open-loop upset dynamics and the impact of flight controllers. However, to date, studies have not considered the effect of time delay on the system’s stability. Current developments at the Airborne Subscale Transport Aircraft Research facility are aimed at testing a subscale generic airliner model during loss-of-control conditions over extended distances and altitudes compared to the generic transport model. In developing controllers for such a remotely piloted vehicle, it is helpful to understand the effect of delay in the communication links and protocols. This paper uses bifurcation an...
