Design of Active Disturbance Rejection Attitude Controller for Vertical Launched Missile

Abstract

There are many problems in the design of attitude control system of vertical launched missile, such as system model nonlinearity, uncertainty, severe aerodynamic parameter perturbation and actuator response delay. Based on Active Disturbance Rejection Control (ADRC), an ADRC attitude controller is designed, which does not rely on accurate mathematical model and can dynamically compensate system model uncertainty and external disturbance. The performance of the controller is verified by using more accurate aerodynamic parameters of the missile. The simulation results show that the attitude controller can make the missile turn quickly and effectively. It can provide a reference for the design of similar missile control system.
