| Abstract: | A blended controller of aerodynamic force and direct thrust is proposed for the characteristic body of kinetic kill vehicles(KKV’s).This controller can make full use of the body lift force,which provides the normal acceleration along with the divert motors.A control law based on the nonlinear disturbance observer is proposed.With the Lyapunov theorem,the proposed controller can guarantee the stabilization of the closed-loop system.Some computer simulation examples show the effectiveness and the feasibility of the suggested methods. |

| Keywords: | nonlinear disturbance observer sliding mode backstepping controller kinetic kill vehicle blended control |
