Abstract
Abstract—A six-degree of freedom (6DOF) mathematical
model for the free fall bomb (FFB) is a crucial factor for
designing a control system. FFB is an unmanned vehicle fired
from a fast-moving airplane on the way to the ground to
follow the assigned target. It might also be referred to as an
air-to-ground smart bomb. Because building a mathematical
model saves time and effort in the domains of control and
testing processes, a nonlinear simulation model of the FFB’s
dynamics should be built using an appropriate CAD tool such
as MATLAB (Simulink). In this work, the FFB aerodynamic
model is estimated using a semi-empirical technique USAF
Missile-DATCOM. To control the attitude of an autonomous
FFB, the mass inertia model is estimated from the CAD tool
and experimental work, and the actuation model is identified
using system identification to describe the servo’s dynamics,
then the dynamic model is built to describe the overall FFB
system. PID controller is one of the best controller types that
is widely used nowadays due to it simplicity, performance,
and implementation. PID controller is designed for the FFB
roll channel to stabilize the FFB’s roll angle. The tracking
performance of the designed controller is verified through
different types of inputs, and the simulation results shows the
superiority of the roll control system.
