Underwater high-precision attitude control method suitable for submarine-launched missile

Abstract

The invention discloses an underwater high-precision attitude control method suitable for a submarine-launched missile, and belongs to the technical field of flight control. The method comprises the steps that (1) acquiring a missile pitching channel instruction, a missile yawing channel instruction and a missile angular speed wherein the missile angular speed comprises a pitching angular speed and a yawing angular speed; (2) filtering the angular velocity of the missile in the step (1) to obtain a filtered angular velocity; (3) determining a pitching channel rudder instruction according to the missile pitching channel attitude instruction in the step (1) and the filtered pitching angle speed in the step (2); (4) determining a yaw channel rudder instruction according to the missile yaw channel attitude instruction in the step (1) and the filtered yaw angular velocity in the step (2); (5) determining a single-rudder instruction according to the pitching channel rudder instruction and the yawing channel rudder instruction obtained in the steps (3)-(4); and (6) driving a spoiler to deflect according to the spoiler deflection angle instruction obtained in the step (5).

Description

technical field [0001] The invention belongs to the technical field of flight control, and in particular relates to an underwater high-precision attitude control method suitable for submarine-launched missiles, which is suitable for submarine-launched missiles controlled by four spoilers. Background technique [0002] The submarine-launched self-defense air defense missile weapon system is a new type of air defense weapon equipment developed by all countries in the world. At present, submarine-launched missiles are developing in the direction of large water depth and high dynamics. In order to meet the launch requirements of the missile in large water depth, the spoiler control method is adopted, and the movement of the missile is controlled by the torque generated by the deflection of the spoiler installed at the tail of the missile. Due to the characteristics of the spoiler itself, there will be channel cross-coupling in the missile controlled by the spoiler. At the same...
