Design of Missile Blended Control System Based on Fuzzy Logic

The blended dynamic model of missile with aerodynamic fin and side thruster is developed. The blended missile control system integrated traditional controller using aerodynamic fin with fuzzy logic controller using side thruster is designed. The parameters are optimized with respect to the tracking performances of missile control system and the criterions of side thruster control based on evolutionary strategies. The simulation results show that the missile control system with side thruster tracks the great maneuver acceleration command accurately and rapidly and the reduced aerodynamic control effectiveness is compensated by the side thruster. The control allocation between the aerodynamic fin and side thruster can be implemented intelligently and correctly.
