Research on taxi trajectory prediction based on conflict detection in surface management system;

Considering Bit-Rock Interaction, anisotropy of bit-cutting and forces applied on the bit etc, a reentry horizontal well trajectory prediction model suited for sliding using BHA with bent housing was presented.

In order to satisfy the online trajectory prediction of multi-machine system,polymerization technology of trajectories was used to reduce the computing burden.

Aiming at the driver's character and using system fuzzy decision theory, some fuzzy evaluation indexes and their membership functions which describe how the driver makes preview course decision based on the front road information and driver himself consideration are established, and the driver course decision behaviors under various road circumstances are simulated.

The essential principles of optimization were introduced,based on which driver preview course model was given through gridding optimization.

The design of X-Y worktable of previewing track;

The track forecast of intersectant objects by general Hough transform;

In consideration of maneuverable ability of missile,a track forecast guidance law is presented to meet the requirement of falling angle and to hit targets precisely based on traditional proportional guidance law.
