A trajectory tracking controller based on switching strategy is presented to solve the problem of strong disturbance and large time delay in parachute system trajectory tracking control. Combining the strong anti-disturbance ability, fast response speed and predictive control of linear auto-disturbance rejection control, the advantages of system delay, high tracking accuracy and good robustness can be overcome effectively. A 2-D trajectory tracking guidance strategy is used to track the parachute trajectory by tracking the heading angle of the target trajectory. In the switching strategy, a dual-switching controller switching rule is designed according to the heading angle deviation, which reduces the switching frequency between controllers and improves the reliability of the dual-controller switching. The simulation results show that the switching controller has better performance than a single controller in tracking a given homing trajectory.
