Nolinear disturbance observer based command filtered backstepping control for missile system

In this paper, a nonlinear disturbance observer based command filtered backstepping control method is proposed for nonlinear missile system in face of multiple disturbances. The proposed method designs a nonlinear disturbance observer to estimate the equivalent disturbances formulated by the multiple disturbances. When the matching condition cannot be met, backstepping method is used to design virtual control law for its recursive nature. Then the estimation of equivalent disturbances is substituted into virtual control laws of all the subsystems to achieve the effect of disturbances compensation and improve the anti-disturbance performance. The numerical simulation results of missile maneuver control demonstrate the efficiency of the proposed control method.
