A trajectory tracking control method based on linear active disturbance rejection control (LADRC) is studied herein to reduce the influence of the nonlinear and coupling characteristics of the parafoil system and environmental disturbances on trajectory tracking control. This method applies guide-based two-dimensional trajectory tracking control strategy and uses a LADRC design controller for the real-time correction of tracking error. In addition, flight simulation and airdrop experiments were conducted under various disturbance conditions. The results showed that the established control method could efficiently overcome the internal and external disturbances, achieve precise trajectory tracking, and showed better robustness and disturbance rejection ability compared with traditional PID controllers.
