Integrated control method for guidance, attitude control, and transformation of hypersonic flight vehicle in diving stage

Abstract

An integrated control method for guidance, attitude control, and transformation of a hypersonic flight vehicle in a diving stage is disclosed. Distance of a current moving target relative to the center of mass of a hypersonic transformation flight vehicle, and latitude and longitude of the moving target are utilized as input of a guidance, attitude control, and transformation integrated control model with a fall angle constraint of the hypersonic transformation flight vehicle in the diving stage, according to a control scheme of the guidance, attitude control, and transformation integrated control model with the fall angle constraint of the hypersonic transformation flight vehicle in the diving stage, an instruction for controlling a rudder deflection angle and transformation rate of the hypersonic transformation flight vehicle is generated, the instruction is input into a six-degree-of-freedom motion model of the hypersonic transformation flight vehicle, and the hypersonic transformation flight vehicle tracks the moving target to complete a flight task. The method controls a lifting force by utilizing transformation characteristics of a flight vehicle, exerts the role of transformation assisted flight vehicle maneuver, enables the task adaptive capability of the flight vehicle to be improved, and effectively solves the problem of difficult coordination between the guidance, control and the transformation of the hypersonic transformation flight vehicle.
