Douglas Ollerenshaw, Auteur ; Costello, Mark, Auteur |Launch uncertainties in uncontrolled direct fire projectiles can lead to significant impact point dispersion, even at relatively short range. A model predictive control scheme for direct fire projectiles is investigated to reduce impact point di[...]
