Tilt launch attitude angle non-leveling real-time correction method of launching vehicle control system

Abstract

The invention provides a tilt launch attitude angle non-leveling real-time correction method of a launching vehicle control system. The method includes the steps that the launching vehicle control system acquires the heeling angle and the trimming angle of a rotary table, the vertical angle and the rotation angle of a launching cradle and the vehicle body azimuth angle; the vehicle body heeling angle and the vehicle body trimming angle are acquired through solution in real time according to the heeling angle of the rotary table, the trimming angle of the rotary table and the rotation angle of the rotary table; the estimated vertical angle of the launching cradle and the estimated rotation angle of the rotary table are solved in real time according to the vehicle body azimuth angle, the vehicle body heeling angle and the vehicle body trimming angle; the altitude angle and the azimuth angle of the launching cradle are calculated according to the vehicle body azimuth angle, the vehicle body heeling angle, the vehicle body trimming angle and the vertical angle and the rotation angle of the launching cradle, and the altitude angle and the azimuth angle of the launching cradle are used as the judgment basis of final control accuracy of the launching cradle. The method has the advantages that the altitude angle and the azimuth angle of the launching cradle are calculated and used as the judgment basis of final control accuracy of the launching cradle, the influence of out-of-level of the rotary table, vehicle body deformation and other factors on the attitude angle of the launching cradle can be avoided, and aiming accuracy is improved.

Description

technical field [0001] The invention relates to a control method, in particular to a real-time correction method for tilted launch attitude angle unleveling of a launch vehicle control system. Background technique [0002] Inclined launch of the launch vehicle is a frequently used launch method for various rockets. In order to accurately hit the target point, it is necessary to calculate the shooting elements of the launcher (that is, the target elevation angle and azimuth of the launcher), and pass Control the erection and rotation of the launcher so that the launcher can accurately reach the position specified by the shooting elements, so the final aiming position accuracy of the vertical rotation of the launcher is an important factor affecting the accuracy of launch. [0003] If the turntable for direction aiming is not level, it will cause a large deviation in aiming, especially if the trunnion on the turntable is not level, the deviation caused by direction aiming is p...
