Weapon Control and Stabilization Using Modern Control Techniques

Modern and future battle field scenario requires future fighting vehicles to have very high pointing and stabilization accuracy while the vehicles are running at their maximum speed on the rough terrain. Even though the conventional control design combined with the strong stabilization(or rate disturbance feed forward) provides some degree of pointing and stabilization accuaracy, it fails to meet the accuracy requirements for the future fighting vehicles. In this paper, weapon control design using recently developed LQG/LTR design methodology will be discussed. Through computer simulation, it will be shown that very demanding position accuracy and stabilization against the wide band stocahstic disturbance induced by vehicle running on the rough terrain are achieved. Digital implementation of this controller and the performance comparison against the conventional controller will also be discussed.
