Abstract

The invention relates to a pre-guidance and attitude stabilization matching guidance method based on nonlinear conversion, and belongs to the technical field of aircraft guidance. The method comprisesthe following steps that the sight angle rate of an aircraft moving relative to a target is measured, and the yaw angle and the yaw angle rate of the aircraft are measured; a sight angle signal is constructed according to the sight angle rate, and an azimuth error signal and a pre-angle error signal are constructed according to the sight angle signal and the yaw angle; an amplitude limiting nonlinear signal is constructed according to the azimuth error signal, and a pre-guidance law is constructed according to the amplitude limiting nonlinear signal and the pre-angle error signal; and an attitude stabilization output signal is constructed according to the pre-guidance law, and an expected course angle of the aircraft is obtained according to the attitude stabilization output signal so that the yaw angle can stably track the expected course angle. According to the method, the problems that guidance law output is rapidly increased, and the missile miss distance is too large are solved.

Description

technical field [0001] The invention relates to the technical field of aircraft guidance, in particular to a method for matching guidance between front guidance and attitude stability based on nonlinear conversion. Background technique [0002] The precise guidance algorithm of the aircraft has a high application value, and can be applied to the automatic landing of the unmanned aerial vehicle, the precise navigation and route planning of the unmanned aerial vehicle, the precise guidance and strike of the unmanned aerial vehicle, etc., the rendezvous and docking of the aerospace vehicle, etc. Therefore, it has been a hot issue for engineers in the field of aircraft design for many years. In particular, the high-precision requirements for the docking of aerospace vehicles and the precise guidance requirements for weapon systems, the accuracy of guidance and guidance is directly related to the success or failure of mission execution. Therefore, precision is the core in the st...
