Abstract :
The dynamics model of ballistic missile is established which spins during the first boosting phase, and its control mechanism is analyzed. Based on the backstepping algorithm, a decentralized sliding mode controller is designed to restrain external disturbances and parameter perturbations. Owing to the bound of the lumped uncertainty is difficult to obtain in advance, an adaptive law is introduced to estimate the value of the lumped uncertainty in real-time. Eventually, the numerical simulation results are given to show the effectiveness of the proposed control scheme.
