Blended Homing Guidance Law Using Fuzzy Logic

Abstract

The application of fuzzy logic for the development of guidance laws for homing missiles is presented. Fuzzy logic approximation of the well known proportional navigation guidance law is discussed, followed by the development of a blended guidance law using fuzzy logic. The objective of the latter guidance law is to combine desirable features of three homing guidance laws to enhance the interception of targets performing uncertain maneuvers. Fuzzy logic guidance law development employs triangular, trapezoidal and sigmoidal membership functions. Mamdani-style inference is employed in the fuzzy inference system. Simulation results using point-mass missile model and a spiraling, high-speed ballistic target model are given.
