Abstract：Aiming at the problem of atmospheric disturbance during the climb of hypersonic aircraft,focusing on the distur-bance of atmospheric density,a vehicle climb command optimization method based on the parameters of the adjacent space environ-ment is proposed.Firstly,the idea of forecasting model based on measured data is introduced,and the Kolmogorov-Smirnov parame-ter calibration method is combined with genetic algorithm to obtain an atmospheric density forecasting model.Then,the optimization model of climb command is established,and the optimal control problem is solved by using Gaussian pseudospectral method and Se-quential Quadratic Programming(SQP).Finally,taking the constant pressure climb of air-breathing hypersonic aircraft as an exam-ple,the simulation results show that this method can quickly and accurately solve the optimization problem of aspirating hypersonic aircraft climb command under atmospheric disturbance,which can meet the relevant requirements and has certain application value.
