Abstract
Abstract
In this paper, the problem of UAV utilizing updraft energy near flight path is modeled, simulated and analyzed. Firstly, a simplified updraft model is established according to the characteristics of updraft. Then, according to the energy trend of UAV in the updraft, the recursive algorithm of UAV energy and the information acquisition model of UAV in the updraft are designed. Based on Nelder-Mead minimum search algorithm, an updraft parameter identification scheme is designed and simulated. It can be concluded that according to the above design scheme, UAV can basically identify the parameters of the updraft region, and achieve a certain identification accuracy, which provides a reference for future research.
