摘要：
According to the problem that the interference may affect the landing accuracy during the landing process of a planetary probe, an anti-interference control method is proposed. Firstly, the landing control model of the planetary probe is established, and the external disturbance of the system is estimated by using the nonlinear disturbance observer. On this basis, an adaptive sliding mode control law is proposed, which makes the system state converge quickly to the equilibrium point. Finally, the method is applied to the Mars landing scene simulation. The results show that the proposed adaptive sliding mode control method can effectively achieve the safe landing of the planetary probe and improve the success rate of the landing mission in the presence of unknown disturbances. © 2019, Editorial Dept. of JA.
