Finite-time sliding mode tracking control for guided projectile

This paper studies the problem of three dimensional tracking control of rolling guided projectile. Via the feedback linearization method, the motion model of the guided projectile is simplified to a nonlinear second order subsystem considering vertical and lateral according to the motion characteristics and aerodynamic. Based on the fast terminal sliding mode manifold and adaptive method, an adaptive finite-time tracking control scheme is proposed which uses adaptive law to handle the unknown upper bound of external disturbances. Lyapunov theory is employed to prove the stability of the system under the proposed control scheme. Also the numerical simulations are carried out to further verify the effectiveness of the tracking control scheme.
