The Research on Optimal Control Method of Missiles' Flight Based on Variable Calculus

To meet the requirements of the tactical targets, in the progress of the missiles’ flight, we often give the related parameters a range to make the targets to extreme. In this paper, we use variable Calculus to learn about the variation of the deflection in missiles’ flight trajectory and the method that can make the missiles reach a certain height in the shortest time. Then with the help of the software—MATLAB, we can get the optimal solution to achieve interceptions and strikes basing on the optimal method in math. It is meaningful for the application of optimization theory in missiles’ control.
