Abstract:

This paper analyzes the models of airborne electro optical pointing and tracking systems, and designs the fuzzy controller based on a genetic algorithm for the gyro stabilized platform system which is the most important component of airborne electro optical pointing and tracking systems.GA is used to optimize fuzzy control rules,parameter,quantification factor and proportion factors. By the particular simulation of the system designed by the fuzzy control based on the genetic algorithm,the result proves that the system performance is very satisfactory.

Key words: gyro-stabilized platform, light of sight, fuzzy control, genetic algorithm, air borne electro-opticalpointing and tracking systems
