Easy Guided Bombs Controller Parameters Design

The simply guided bomb(SGB) is researched in this paper. The forces and moments acting on the bomb are analyzed and the corresponding reference frames and motion model are built .Based on disturbance theory ,the mathematical model is simplified .Because of the similarity between the motion in vertical plane and the motion in the horizontal plane, Dynamic characteristics of the motion in vertical plane is mainly studied. When the simple guided-bomb is cast under low altitude or low heading stance,The methods of PD control and PID control are established and the corresponding parameters are got with the methods of frequency design.At the same time, When the simple guided-bomb is cast under high altitude or high heading stance, pneumatic coefficients become non-linear,the PID control of back propagation neural network and fuzzy PID control are separately adopted.The simulation results proves the control method is perfect and robust.Finally,digital simulation is finished , digital simulation proves the rationality of the controller parameters by the classical control theory.
