Abstract

The invention provides a method for performance evaluation of a spacecraft attitude control ground simulation system. According to the method, the credibility of a dynamic system, a kinematics system, a measurement system and a control system is studied based on the simulation system credibility theory, the overall credibility of the spacecraft attitude control ground simulation system is obtained through comprehensive calculation, and then the performance of the spacecraft attitude control ground simulation system is evaluated. According to the evaluation method, the credibility of the ground simulation system and an actual satellite attitude control system is considered from all aspects, simulation data are fully utilized, and the credibility of the ground simulation system is described objectively and quantitatively; the theoretical basis is reliable, the calculation process is simple, the application range is wide, and a new idea and reference are provided for performance evaluation study of other simulation systems.

Description

technical field [0001] The invention relates to measurement technology, in particular to a method for evaluating the effectiveness of a space vehicle attitude control ground simulation system. Background technique [0002] Once the space vehicle is launched, it will be difficult to maintain, and its special operating environment makes the ground simulation test very important. A key issue in the development of the ground simulation system is how to analyze the reliability of the ground simulation system, that is, its effectiveness evaluation problem Therefore, it is of great significance to study the performance evaluation method of the space vehicle ground simulation system for the development and analysis of the simulation system. The analysis results are directly related to the performance of the simulation system, the rationality, necessity and credibility of the indicators. [0003] Another formulation of effectiveness analysis is the credibility of the simulation syste...

Problems solved by technology

However, this evaluation method relies on expert experience in the process of calculating the credibility weight coefficient. Whether it uses scoring or other quantitative means, it is essentially a qualitative evaluation and lacks effective quantitative analysis support.

In addition, it is difficult for this method to make full use of authoritative models and valid data, which affects the objectivity and persuasiveness of the evaluation conclusions

[0007] In the paper "Study on the Effectiveness of Air-floating Physical Simulation System for Space Robots" (Space Control Technology and Application, Volume 36, Issue 6, Pages 33-38), Zheng Yongjie, Zhang Duzhou and other scholars from Beijing Institute of Control Engineering discussed However, it cannot be generally applied to the effectiveness evaluation of other aircraft ground simulation systems.

[0008] Scholar Jia Jie from Northwestern Polytechnical University proposed a spacecraft semi-physical simulation The effectiveness analysis method of the system, but this method has many evaluation parameters, some parameters are difficult to determine in practical applications, and this method is only for semi-physical simulation systems, not for full-physics simulation systems
