Nonlinear guidance techniques for agile missiles

The paper presents new approaches to the guidance of agile missiles. They a re based on nonlinear discontinuous control techniques applied to the gener ation of guidance laws capable of taking advantage of the vehicle's post-st all capabilities, Agility and maneuverability requirements imply a higher b andwidth and robustness for the guidance loop. which are addressed by a var iable structure controller format. Formal stability considerations are pres ented, and the guidance structures are validated using nonlinear simulation . (C) 2001 Published by Elsevier Science Ltd.
