In this paper,the method of energy control is used to discuss a Fuel-Optimal Flight trajectory optimization problem of UAV(unmanned aerial vehicle).The point-mass motion model based on energy states is founded and simplify the dimension of the traditional point-mass motion model.It adopts the variational method the performance requirement based on energy control is proposed,and the optimal equations of longitudinal flight process are obtained.A suitable arithmetic and the optimizing program are in Matlab.The simulation results show that this method is exact and it can enhance the efficiency,save the fuel,lengthen the cruise time,augment the voyage.
