This paper proposes to equal the term of coupling to outer disturbance, and uses the dynamic full-order sliding mode variable structure controller with integral compensation to make three-axis move within their own sliding modes and realize the aim of decoupling and robust to disturbance and parameter perturbation.

A HP nonlinear guidance law is presented based on the second-order sliding mode control theory,considering the kinematics of interception and the uncertainty of target acceleration.

Second-order sliding mode technique is used for the stimation.

A novel second-order sliding model control (SOSMC) was proposed aiming at the inherent chattering of classical sliding mode control for high-precision attitude control of flexible launch vehicles, and the control law was designed according to super-twisting algorithm.

Thus,the second order sliding mode controller based on singular perturbation theory was proposed.

Meanwhile,high-order sliding modes are utilized to eliminate the chattering phenomenon,and to guarantee the stability of the system.

Combined with the derivative estimator,the nonsingular terminal sliding mode manifold was utilized and the high-order sliding mode control strategy was designed to drive the states of the input-output subsystem to the equilibrium points within finite time,and drive the states of the internal dynamic subsystem to the neighborhood of the equilibrium points.
