Modified linear theory and Kalman filtering for in flight projectile impact point prediction

Creator:

Hainz, Leonard C.

Abstract:

A method for real time in-flight prediction of the ground impact point of an indirect fire projectile is investigated. The method investigated is comprised of a combination of an impact point predictor and an extended Kalman filter state estimator based on modified linear theory. The modified linear theory model is...

Model predictive control of a direct fire projectile equipped with canards

Creator:

Ollerenshaw, Douglas R.

Abstract:

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 dispersion. The control law depends on projectile linear theory to create an approximate linear model of...
