Missile GNC To Intercept Trajectories

A Brief Synopsis

Guidance, Navigation, and Control (GNC) System allows a complicated system to estimate its state, determine its next trajectory, and steps to achieve that determined trajectory. In this project, a GNC model is implemented for a missile to successfully intercept a target projectile. To simplify the model, only longitudinal dynamics of the missile are analyzed. Accordingly, the height of the missile and distance along the ground are the only elements of interest. This is referred to as ”short period approximation”, through which the longitudinal dynamics are determined at the equilibrium where thrust effects are considered to be zero and only the torque generated from elevators is considered. For state estimation, an observer is designed and simple trigonometry is used as the mathematical framework for the guidance model. The entire control architecture along with the system dynamics is implemented in Simulink.
