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.

Embodiment Construction
[0040] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0041] It should be noted that, in the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other; and, based on the embodiments in the present disclosure, those of ordinary skill in the art obtained without creative work All other embodiments belong to the protection scope of the present disclosure.
[0042] Theoretical technology of the present invention is briefly described as follows:
[0043] In order to realize the three-axis exchange and the reconfiguration capability under any single wheel damage, for the three axes, at least two of the four momentum wheels should provide two complementary components, and a total of six components are required. According to the design that each wheel has two different axial components, the momentum wheel set can provide a total of eight components. Obvio...

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...
