Abstract

The invention discloses an attitude control parameter self-adaptive adjustment method and device, electronic equipment and a storage medium. The attitude control parameter self-adaptive adjustment method comprises the steps that the engine apparent velocity increment and the flying pressure of a rocket are obtained; the control surface control efficiency of the rocket is calculated by using the engine apparent velocity increment and the flying pressure; and attitude control parameters of the rocket is calculated by using the control surface control efficiency of the rocket. By the adoption ofthe technical scheme, the attitude control parameters can be directly associated with the flight state estimated on the rocket, the matching degree of the attitude control parameters and the real flight state under different launching conditions is improved, and the problem that the rocket is out of control is avoided.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an attitude control parameter self-adaptive adjustment method, device, electronic equipment and storage medium. Background technique [0002] For the attitude control design of traditional launch vehicles, after selecting the three-channel attitude control parameters of several standard trajectory feature points, usually in the six-degree-of-freedom mathematical simulation of the rocket body movement, half-physical simulation or actual flight test, relative to the take-off time The flight time is the node, and the real-time attitude control parameters are calculated by linear interpolation, and the attitude control loop is introduced to drive the actuator of the control system. [0003] In recent years, the rapid development of the commercial aerospace field has put forward more requirements for rapid response launch vehicles. For this reason, commercial launch vehicles need t...
