机载风力发电机的目的是通过控制系留翼沿逆风路径飞行的气动升力来产生可再生能源。在风速和风向信息有限的情况下，优化这种发电机的运行问题被认为是，旨在最大限度地提高开发的平均功率。首先，研究了一般路径参数化的牵引力。然后，利用该分析的结果来设计算法，以实时最大化力，从而最大化功率。该算法只使用测得的系绳上的牵引力，它能够适应系统的操作，以最大限度地提高不确定和时变风的平均力。数值仿真结果表明了该方法的有效性。
Airborne wind energy generators aim to produce renewable energy by means of aerodynamic lift from tethered wings controlled to fly crosswind paths. The problem of optimizing the operation of such a generator in presence of limited information on wind speed and direction is considered, aiming to maximize the average power developed. First, a study of the traction force is presented for a general path parametrization. Then, the results of this analysis are exploited to design an algorithm to maximize the force, hence the power, in real-time. The algorithm uses only the measured traction force on the tether, and it is able to adapt the system's operation to maximize the average force with uncertain and time-varying wind. Numerical simulations are presented to highlight the effectiveness of the approach.
