Abstract

In this paper, the mathematical modeling of the country race in 2014 title A - Chang E III aircraft lunar soft landing problem for background, determined the location of nearly Apo lune, and solved various stages of parameters to obtain a series of reasonable conclusions. First, the use of two-point boundary value dynamics model, discrete continuous process, solved for the location of nearly Apolune. Then analyzing the various stages of the soft landing, the key point is to state constraints to optimize the index to establish minimum energy optimal control model, and iterative calculations to get the aircraft away from the lunar surface height and quality changes over time case. The minimum energy consumption was 1.16t. And finally, do a sensitivity analysis to verify that the system has strong stability and robustness.
