Reachable Set Control For Preferred Axis Homing Missiles

This paper presents the results of a linear control technique developed for fixed-final-time constrained systems and applied to preferred axis homing missiles. This technique accommodated the nonlinearities, constraints, and the modeling errors of a suboptimal linear design to maintain the target within the missile reachable set. This feature minimized miss distances, and prevented control saturation during the terminal portion of the trajectory.
