Problems solved by technology

However, at present, the torque distribution from the three-dimensional space to the wheel train space is usually carried out in a pseudo-inverse way. Although this method has the characteristics of energy optimization, it also leads to a large torque output of a certain momentum wheel, and the accumulation of angular momentum is too fast. The output capability of the entire momentum wheel combination is limited, and the maximum angular momentum envelope surface of the wheel train cannot be reached

Abstract

The invention relates to a momentum wheel driving torque distribution method with a maximum angular momentum envelope, and belongs to the technical field of satellite attitude maneuver control. The method is mainly for a momentum wheel used for the satellite attitude control, and improves the angular momentum output of a satellite momentum wheel set. In theory, the maximum envelope surface of theangular momentum of the momentum wheel set can be achieved. The momentum wheel driving torque distribution method adopts a momentum wheel torque dynamic distribution and an angular momentum feedback tracking method, thereby improving the angular momentum output capability of the momentum wheel set. Compared with a pseudo-reverse distribution method usually adopted by a momentum wheel train, the momentum wheel driving torque distribution method can effectively expand the angular momentum envelope of the momentum wheel train and greatly improves the attitude maneuverability of a wheel control satellite.

Description

technical field [0001] The invention relates to a satellite momentum wheel driving torque distribution method with the maximum angular momentum envelope, and belongs to the technical field of satellite attitude maneuver control. Background technique [0002] At present, satellites in orbit usually use a momentum wheel combination for high-stability attitude control. The momentum wheel set installed non-coaxially outputs a three-axis attitude control torque to achieve attitude stability and attitude maneuvering of the satellite. However, at present, the torque distribution from the three-dimensional space to the wheel train space is usually carried out in a pseudo-inverse way. Although this method has the characteristics of energy optimization, it also leads to a large torque output of a certain momentum wheel, and the accumulation of angular momentum is too fast. The output capability of the entire momentum wheel combination is limited, and the maximum angular momentum envel...
