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.
