摘要：
A second-order dynamic terminal sliding mode control is proposed for near space vehicle with high speed, violent changes of aerodynamic parameters, large external disturbance. To achieve high precision and overcome chattering which usually exists in conventional sliding mode control, second-order dynamic sliding mode control is combined with terminal sliding mode control. The terminal sliding mode control speeds up convergence of tracking error and the second-order dynamic sliding mode control obtains continuous controller in time domain by embedding discontinuous functions into the first-order differential of controller. Finally, the simulation applied to near space vehicle demonstrates the superiority and effectiveness of the control scheme.
