Comparative Analysis of the Guided Bomb Flight Control System for Different Initial Conditions

The article presents research on the influence of initial conditions on the self-guidance of a guided bomb towards a stationary ground target. The aim of the study was to investigate the correlation between the initial tilt angle of the guided bomb and the precision of impact, as well as the time required to reach the surface target. To fulfil this purpose, the flight control system of the guided bomb needed to be designed accordingly. The need to develop these systems arises from emerging information that Ukraine and Israel are converting unguided bombs into precision-guided ones. This justification is based on objective reasons. The article analyses the application of classical controllers: PI, PD and PID. Their task was to accurately guide a stationary ground target under various initial conditions. A preliminary method has been proposed for selecting optimal gain coefficients for the PID controller, which constitutes the main component of the autopilot of the guided bomb flight control system. A proprietary interpolation method was suggested, starting with the use of an optimization function in MATLAB software. The numerical findings are presented in a graphical manner.
