Aiming at the pitching movement model, a nonlinear variable structure controller with an optimal sliding surface for the pitching control system of missile was presented.

The simulation methods for pitching movement I going off course and rolling of spaceships are described, and the vision simulation of moving conditions could be realized.

This article mainly introduces the principle of the multi-level recursive prediction method and the first application example to the pitching movement prediction of a large-sized naval vessel.
