Abstract: Based on the standard ballistic, an improved longitudinal guidance law for reentry vehicle is proposed, which is deduced from compensation ideas. By using the unknown perturbation function, the longitudinal dynamics equation is described. Based on the equation, a guidance law is designed to adapt the changes of atmospheric parameters. The whole control contains the standard guidance law and adaptive compensation guidance law. The simulation results show that the designed control law can compensate the changes of aerodynamic parameters and atmospheric density.

Key words: reentry vehicle, longitudinal guidance, standard trajectory, compensation, adaptive control
