Trajectory Optimization of Long-Enduradnce Flight Energy-based Control

In this paper, the method of energy control is used to disduss the trajectory optimization problem of long-en- duradnce economizing gasoline flight. The point-mass motion model based on energy states is founded, simplify the di- mension 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 lognitudinal flight process are obtained. It adpots the total optimal solution of the flight process, a suitable arithmetic,and the optimizing program in Mstlab. The simulation re- sults shows that this method can save the fuel,lengthen the cruise time,augment the voyage.
