Application of Active Disturbance Rejection Control Technology in Missile with Thrust Vector Control

Abstract

A design method of thrust vector control missile attitude control system is presented in this paper. Firstly, the short period motion model of thrust vector missile is established. Secondly the attitude controllers of pitch, yaw and roll channels are designed based on ADRC (Active disturbance rejection control technology), and the control structures of pitch, yaw and roll channels are given. In pitch (yaw, roll) channel, the pitch (yaw, roll) angular velocity loop is used to track the command of pitch (yaw, roll) angular velocity rapidly, and the angle of attack (sideslip angle, roll angle) loop is used to track the command of angle of attack (sideslip angle, roll angle) rapidly. Finally, the stability of the designed closed-loop system is proved by Lyapunov method. The thrust vector control missile model designed by this method is simulated numerically, and the results show that the designed missile attitude has good response characteristics.
