Trajectory planning method

Abstract

The invention aims at overcoming the defect that a traditional trajectory planning method applied to a guided missile having turning capability, for example a boosting glided missile, has inadaptability and provides a trajectory planning method. According to the trajectory planning method, human intelligence factors are introduced, trajectory characteristics are directly designed based on an analytic curve, control quantity and restraint conditions are inversely calculated, the intension of a designer and the planning process of a computer are organically integrated through a rough draft interaction technique, the vision of the trajectory planning process is remarkably improved, and the boosting glided missile trajectory planning efficiency under complicated constraint is improved.

Description

technical field [0001] The invention relates to the technical field of ballistic planning, in particular to a dynamic inverse ballistic planning method in a sketch interactive virtual domain for calculating ballistic parameters through a curve shape. Background technique [0002] With the approach of the full deployment of the missile defense system, various military powers are currently competing to research missiles with certain maneuverability in order to improve the missile penetration capability and maintain the missile strike capability. However, most of these missiles fly in the atmosphere. While meeting launch constraints and mission requirements, constraints such as energy, overload, heat flow, and dynamic pressure must be considered, which greatly increases the complexity of the missile flight process. How to plan the flight trajectory and improve combat effectiveness under complex constraints is a major challenge for this type of missile combat application. [00...

Problems solved by technology

For example, the existing virtual domain dynamic inverse method is proposed under the framework of optimal control theory. Its purpose is to solve the guidance problem. The method of dealing with the two-point boundary value problem is used to solve the trajectory planning problem. Generally, the position parameters of the starting point and the ending point can be calculated. Adjustment, but the process parameters such as flight trajectory cannot be adjusted by human-computer interaction, so it does not have the ability to interactively adjust the trajectory
