Integration of a fuzzy guidance-control system for a command interceptor against hypersonic target

Abstract

Extensive research efforts have been made to design or improve flight guidance and control systems. With the phenomenal growth in soft computing techniques, there is a growing interest to apply these techniques to missile flight guidance and control systems. This paper investigates the application of fuzzy logic for the development of fuzzy guidance laws for command-to-line-of-sight skid-to-turn (CLOS-STT) missile. The fuzzy logic guidance scheme based on the well known three-point guidance law is discussed. Preliminary studies have shown the advantages of using anti-air tactical missiles against hypersonic ballistic targets. A complete six-degrees-of-freedom (6-DOF)-flight model for an anti-air command guidance system is developed. Simulation results for this three-dimensional missile-target interception process are given to show the effectiveness of the proposed fuzzy guidance scheme.
