| 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. | ||
