摘　　要：探讨了小型无人机如何通过从大气扰动中获取能量来达到提高航程航时的目的。基于纵向质点模型建立了纵向运动学模型以及动力学模型,在此基础上得到飞行单位距离的能量改变量的函数,构造优化模型把能量获取问题转化为轨迹优化问题,并引入稳定平衡条件进行求解,同时进行控制律的设计,并在Matlab/Simu-link中对模型以及控制律的有效性进行了仿真验证。How to improve the range and endurance by extract energy from atmospheric turbulence of the small Unmanned Aerial Vehicles（UAV） were discussed in this paper.A longitudinal mass model was used to establish the vehicle kinematics model,the dynamics model and the function of energy change per flight distance.With the help of the models,the optimization model of transforming the energy extraction to the trajectory optimization is built.A stable balance condition was used to solve the optimization problem and the control law was designed.Finally,the effectiveness of the model and the control law is simulated with the Matlab / Simulink.
