Design of Missile Control System Based on State Output Feedback Adaptive Fuzzy Control

Abstract

Aiming at the problem of airborne missile reaction thrust/aerodynamic compound control, a reaction thrust/aerodynamic compound control system based on fuzzy logic and model reference adaptive control (MRAC) is proposed.Firstly, the mathematical model on the pitch channel of the reaction thrust/aerodynamic airborne missile is established, and the pneumatic ruder and reaction thrust/aerodynamic compound three-loop autopilot are designed.For the problem that the reaction thrust of the compound autopilot is difficult to control, the fuzzy logic is introduced to control the working time of the reaction thrust device and set a more appropriate distribution ratio.The output of the state space is used as feedback to build a model reference adaptive algorithm to optimize the system and to reduce the overshoot of the system.The simulation results show that the control system designed by fuzzy logic and MRAC can make the reaction thrust/aerodynamic airborne missile track the input command faster and more accurately.
