Design and Simulation of Trajectory Tracking Guidance Law Based on LQR for Target Missile

Abstract

Aiming at the trajectory tracking problem of the target projectile, a ballistic tracking guidance law of the target projectile is designed based on the linear quadratic regulator (LQR) theory. Using time as an independent variable, the motion equation of the center of mass of the target bomb was linearized using the small disturbance method to establish the center of mass motion of the Space expressions; The LQR theory was used to design the trajectory tracking guidance law of the target projectile. Finally, the semi-physical simulation test was conducted to verify the trajectory tracking guidance law of the designed target projectile.
