Trajectory Tracking Study based on Integrated Guidance and Control

Abstract

For gliding range-extended rocket, the range-extending problem is translated to tracking issue against gliding project trajectory. Integrated guidance and control method is studied aiming to improve the tracking performance of classic guidance and control law. Firstly, the study problem and background are introduced in the introduction part. Then the models of rocket dynamics, relative kinematics between the rocket and target, integrated guidance and control are all established in the second part of this paper. In the next two parts, the integrated guidance and control law is designed based on ADRC and compared with the classic method through mathematic simulation. The classic method uses PID control law and PN guidance law. Simulation result shows that the integrated method can deal with greater disturbance and can effectively improve the quality of dynamical response.
