A new predictive guidance law for moving-mass actuated reentry vehicle is presented in this paper. The proposed approach is based on the fact that lateral force is formed in a plane which is perpendicular to the reentry vehicle velocity. Particularly, the nominal impact point is defined as the impact point generated by zero lift trajectory. The virtual displacement is defined as the tiny change of the nominal impact point, which is caused by any instantaneous lateral force at the beginning of the trajectory. The optimal direction of the lateral force is obtained by the solution of optimal virtual displacement, in which the optimal virtual displacement should point to the target. The linear quadratic gauss (LQG) method and the analytical solution of the reentry trajectory are used in this guidance method. Simulation results demonstrate the effectiveness of the proposed method.

The moving-mass hypersonic attitude dynamic model is a strong nonlinear, multivariable, and strong coupling system. Based on the reasonable assumption, a simplified dynamic model is given. According to the time-scale separation theory, a sliding variable structure controller is designed and implemented for the tracking control of angular velocity and angle at the same time. Simulation results demonstrate the effectiveness of controller.
