Title The terminal proportional navigation simulation and design of the guided projectile
Abstract In the Matlab software environment,the terminal navigation law of the guided projectile was designed and simulated.Established the 2D and 3D relative motion equations about the guided projectile and the target.Outlined the basic composition of the navigation and control system of the guided projectile.The Single-variable control method was applied to discuss the 3D spread of uncontrolled projectile impact points when there were random initial perturbations and calculate the deviation.The 2D PN model was established to analyze the affect of the proportional coefficient for guiding performance.
Designed the terminal guidance law of 3D attacking the ground fixed target respectively based on the impact point predition method and the traditional PN,and the traditional PN of attacking the ground moving target,and applied the relative velocity ratio to modify the PN coefficient,so that established a new kind of PN.Through simulation to analysis the ballistic performance and shooting accuracy of the four terminal navigation scheme when considering the overload limiter and inertial delay.
