Abstract

The invention discloses a sample data generation method and device and a computer readable storage medium. The sample data generation method comprises the steps: establishing a fuel optimal control problem model for rocket vertical recovery; establishing a corresponding inverse problem model according to the fuel optimal control problem model; and generating sample data according to the inverse problem model. According to the scheme provided by the embodiment of the invention, the sample data is generated based on the inverse problem model, the problem of forward solving of fuel optimization is avoided, the consumed time is less, and the sample generation efficiency is higher.

Description

technical field [0001] This article relates to intelligent control technology, especially a sample data generation method, device, and storage medium. Background technique [0002] As international commercial rocket companies such as SpaceX (SpaceX) and Blue Origin (Blue Origin) have successfully developed reusable rocket vehicles, rocket vertical recovery technology has become a research hotspot in academia and the world's major space agencies. When the first stage of the rocket completes its launch mission and then enters and returns, it is subject to many uncertain disturbances such as the dense atmosphere, which poses a severe test to the precise landing guidance algorithm. Due to the uncertainty of the initial conditions and the short descent time of the rocket, the traditional algorithm cannot meet the requirements of strong adaptability and real-time performance. Contents of the invention [0003] Embodiments of the present application provide a sample data generat...
