Research on Rocket Launcher Position Servo System Based on the Reaim

In response to the existing strong disturbance of gas flow in the state of launch for the rocket launcher,which makes the gun tube deviate from the initial position after launching,the rocket servo system based on reaim is put forward.The system mathematical model is established based on rocket servo system,and then through the use of the theory of ADRC,nonlinear extended state observer and the corresponding control law are designed so as to weaken the impact of strong disturbance on the system firing accuracy and improve the speed and precision of reaim of the rocket launcher.Digital simulation results show that the system has a good tracking performance,and that under the disturbance of gas flow,the system can quickly return to the initial position,with the effectiveness of the proposed method proved.
