In this paper, trajectory prediction and control design for a desired hit point of a projectile is studied. Projectiles are subject to environment noise such as wind effect and measurement noise. In addition, mathematical models of projectiles contain a large number of important states that should be taken into account for having a realistic prediction. Furthermore, dynamics of projectiles contain nonlinear functions such as monomials and sine functions. To address all these issues we formulate…

Modified Projectile Linear Theory for Rapid Trajectory Prediction

In some smart weapons, estimation of the impact point of the shell at each computation cycle of the control law is an integral part of the control strategy. In these situations, the impact point

Model Predictive Control of a Direct Fire Projectile Equipped with Canards

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

Impact Point Prediction for Thrusting Projectiles in the Presence of Wind

TLDR
Based on the multiple interacting multiple model (MIMM) approach developed recently, the IPP performance is investigated with respect to the total observation time and the sensor accuracy in various wind scenarios and shows that it can be fully compensated if the wind information is available.

Impact point model predictive control of a spin-stabilized projectile with instability protection

Most smart projectile control systems generate lateral control forces to guide the round to a target. Experience has shown that under the right combination of body orientation, translational

Stochastic Model Predictive Control for Guided Projectiles Under Impact Area Constraints

TLDR
A stochastic model predictive guidance algorithm is developed, which incorporates nonlinear uncertainty propagation to predict the impact probability density in real-time and produces a guidance law that can achieve minimum miss distance while avoiding impact area constraints.

Linearized Motion of a Fin-Stabilized Projectile Subjected to a Lateral Impulse

An existing analytical theory for modeling the free-e ight motion of nonspinning, statically stable projectiles is extended to include the effect of a simple lateral impulse applied during e ight.

Nonlinear estimation techniques for impact point prediction of ballistic targets

TLDR
The three filtering techniques are compared to the theoretical Cramer-Rao lower bounds (CRLB) of estimation error and the performance and accuracy of the EKF, UKF, and the chosen Particle Filter implementation for impact point prediction are compared.

TLDR
A procedure to increase the size of the semidefinite program, leading to increasingly accurate approximations to the true optimal control strategy, is given.
