In order to recover the rocket booster safely and efficiently, researches on the controllable parafoils recovery are gradually carried out in this field. Aiming at the problem of the sideslip angle caused by external disturbances such as crosswind in the actual flight process of the parafoil first-stage booster combination (PFC), an improved guidance law with sideslip-compensation basing on line-of-sight (LOS) is proposed to achieve accurate tracking of the desired path in Serret-Frenet (SF) coordinate system. The ADRC controller is applied to control the attitude angle of the parafoil rigid body model with 6-degree-of-freedom (6-DOF), and to estimate and compensate for disturbances. The simulation experiment verifies that the path tracking strategy has the strong points of fast convergence, strong immunity from interference and small tracking error.
