Momentum wheel set configuration design and control distribution method under harsh envelope constraint

Abstract

The invention provides a momentum wheel set configuration design and control distribution method under harsh envelope constraint. The method comprises the following steps: arranging a momentum wheel set; determining envelope control and distribution exchange capability parameters of the momentum wheel set; and configuration parameters and attitude control distribution parameters of the momentum wheel set are determined. According to the momentum wheel set configuration design and control distribution method under the harsh envelope constraint, the problems that according to a traditional method, design is difficult to standardize, the installation envelope requirement is large, wheel sets are installed in a scattered mode, and capacity distribution of all shafts is unreasonable are solved; the momentum wheel set configuration design and control distribution method meeting strict installation space envelope, three-axis exchange capability optimization and any single-wheel damage reconstruction is realized, and the method has the following advantages: 1) the requirement of the strict installation space envelope is met; 2) the standardized wheel set configuration design and the control distribution process can be realized; 3) the exchange capability is distributed more reasonably; and 4) the method has an abnormal reconstruction capability under any single-round damage.

Description

technical field [0001] The invention relates to the technical field of momentum wheel set design and control, in particular to a momentum wheel set configuration design and control distribution method under strict envelope constraints. Background technique [0002] In the design of the satellite attitude and orbit control subsystem, the momentum wheel is the most common and important actuator. In order to maximize the angular momentum exchange capacity of the momentum wheel, its appearance is usually in the shape of a round cake. The installation of the momentum wheel set needs to consider its appearance constraints . In addition, in order to realize the three-axis attitude control of the satellite, it is necessary to install more than three momentum wheels and point to different directions to form the three-axis exchange capability and provide the reconstruction capability when a single wheel is damaged. [0003] Satisfying the external installation constraints of momentum...

AI Technical Summary

Problems solved by technology

[0006] In summary, the existing installation configuration of the momentum wheel set is difficult to meet the requirements of small installation space, strict envelope constraints, and the need to optimize the three-axis exchange capacity according to the inertia characteristics of the satellite, and cannot provide the reconstruction capability under any single wheel damage. The installation envelope is too large, it is difficult to install in a centralized manner, and the exchange capacity distribution of each axis is unreasonable, etc.
