Hypersonic flight vehicle dive segment full amount integration guidance control method

Abstract

The invention provides a hypersonic flight vehicle dive segment full amount integration guidance control method. A technical scheme is characterized in that firstly, a sensor measures states of a hypersonic flight vehicle relative to a ground system, wherein the states comprise a speed, a speed inclination angle, a track yaw angle, a rolling angular speed, a yaw angular speed, a pitching angular speed, a pitch angle, a yaw angle, a rolling angle and the like; then the above obtained quantities of states, positional information of an object relative to the ground system and a control parameter are substituted into a formula so as to calculate a rudder deflection angle vector, wherein the positional information is measured in advance; finally, the rudder deflection angle vector is used to control the hypersonic flight vehicle. In the invention, based on an aircraft full amount coupling integration guidance control model, an adaptive-block dynamic surface inversion method is used to realize integrated guidance control, and a problem of repeated design can be effectively avoided so that time and economic cost of a guidance control system design are reduced.

Description
