Description

technical field [0001] The invention relates to a method for processing fuel consumption constraints in a spacecraft flight game, in particular to a method for processing the fuel consumption constraints of two spacecraft when the game is played between two spacecraft, and belongs to the field of aerospace. Background technique [0002] In the future space game confrontation mission, the problem of spacecraft pursuit and escape plays an important role. The characteristic of the spacecraft game problem is that the spacecraft participating in the game are all capable of maneuvering, one side is the chaser, and the other side is the evader. The chaser completes the pursuit of the evader in the shortest possible time, the evader tries to prolong the game time, and there is no cooperation between the chaser and the evader. The solution to the game problem, that is, how the chaser can complete the capture of the evader in the shortest time, is an important part of the overall pla...

Problems solved by technology

However, this method cannot guarantee the optimality of the trajectories of the two spacecraft, and does not consider the mass change of the spacecraft, so it cannot solve the spacecraft differential game problem considering the fuel consumption constraint

[0004] Prior technology [2] (see Shen H-X, Casalino L. Revisit of the Three-Dimensional Orbital Pursuit-Evasion Game [J]. Journal of Guidance, Control, and Dynamics, 2018, 41(8): 1823–1831), using The indirect method is optimized, and the three-dimensional orbital pursuit and escape problem considering mass consumption is studied. However, adding the fuel consumption constraint of the spacecraft will reduce the convergence area of ​​the problem and make the convergence worse, so it is impossible to solve this kind of problem considering the fuel consumption constraint.
