Attitude control shift handover method and system during middle-terminal guidance shift handover

Abstract

The invention discloses an attitude control shift handover method and system during mid-terminal guidance shift handover. According to the invention, research is carried out based on attitude control shift handover problems caused by different guidance instructions under different mid-terminal guidance systems; and corresponding control strategies and control parameters are completely different due to the fact that the guidance instructions are different and control types corresponding to controlled objects are different, so that when switching is carried out between the guidance instructions, it is possible to cause jumping of a control instruction and a violent change of missile body attitude, and for a strapdown seeker with a small field of view, it is likely to cause target lock losing. Therefore, the invention designs an attitude control shift handover algorithm for the situation to ensure stable transition of the missile body attitude during the mid-terminal guidance shift handover.

Description

technical field [0001] The invention relates to an attitude control handover method and system when the middle and last guidance is handed over, and belongs to the technical field of guidance control of tactical missiles. Background technique [0002] At present, in-depth research has been carried out on the transition of mid-to-late guidance in the existing technology, and a variety of more effective technologies have also been proposed, but most of them are based on the situation that the guidance instructions of the mid-to-late guidance are the same, so that the The jump variable of the guidance command is limited to a small value range, that is, the attitude of the missile body transitions smoothly before and after the transition of the mid-to-terminal guidance, and the transition of the mid-to-terminal guidance is successfully completed (the smooth transition of the attitude of the missile body is the key point during the transition of the mid-to-terminal guidance) . ...

AI Technical Summary

Problems solved by technology

[0003] However, with the development of guidance technology, different guidance systems and guidance instructions are adopted before and after the shift, that is, there is a problem of attitude control handover under different systems for the middle and final guidance instructions. The guidance instructions are different, and the control types corresponding to the controlled objects are different. , so the corresponding control strategy and control parameters are completely different. When the two are switched, the control command jumps, resulting in a drastic change in the attitude of the projectile. For a strapdown seeker with a small field of view, it is easy to cause the target Lost lock
