摘要翻译:
热飞翔节省了许多能源,但这种形式的大距离飞行对鸟类、人和无人机来说是一个巨大的挑战。解决办法是利用所谓的热气,热气是大气中局部的、较温暖的区域,以超过鸟类和飞机下降速度的速度向上移动。通过更有效地利用环境来节省能源也是自主无人机的一个重要可能性。近年来,针对无人机的控制策略在仿真和实际应用中得到了成功的发展。本文首先介绍了我们对飞翔飞行和飞翔策略的认识,然后讨论了飞翔无人机在模拟和实际平台上的应用中所开发的控制策略。为了提高热工开采策略模拟的精度,提出了一种考虑湍流影响的方法。最后,我们提出了一种新的GPS独立控制策略来开发热上升气流。

英文摘要:
Thermal soaring saves much energy, but flying large distances in this form represents a great challenge for birds, people and Unmanned Aerial Vehicles (UAVs). The solution is to make use of so-called thermals, which are localized, warmer regions in the atmosphere moving upwards with a speed exceeding the descent rate of birds and planes. Saving energy by exploiting the environment more efficiently is an important possibility for autonomous UAVs as well. Successful control strategies have been developed recently for UAVs in simulations and in real applications. This paper first presents an overview of our knowledge of the soaring flight and strategy of birds, followed by a discussion of control strategies that have been developed for soaring UAVs both in simulations and applications on real platforms. To improve the accuracy of simulation of thermal exploitation strategies we propose a method to take into account the effect of turbulence. Finally we propose a new GPS independent control strategy for exploiting thermal updraft.
