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

technical field [0001] The invention belongs to the field of aircraft guidance and control, and in particular relates to a hypersonic aircraft dive section full coupling integrated guidance and control method with drop angle constraints. Background technique [0002] The hypersonic vehicle adopts a high-lift-to-drag ratio shape, which can realize long-distance autonomous navigation. Due to its high flight Mach number, it has many outstanding capabilities, mainly including rapid response capability, strong penetration capability, high-efficiency destruction capability, large maneuverability, etc. It is highly valued by major countries in the world and has a wide range of military applications. value and prospects. During the dive phase, the hypersonic vehicle has the characteristics of large Mach number variation range and large overload, the state of the vehicle will change drastically, and the motion of the center of mass and the motion around the center of mass present th...
