Optimal distribution method of uniaxial batch reaction flywheel torque based on angular momentum margin

Abstract

The invention discloses a single-shaft batch counteractive flywheel moment optimal distribution method based on an angular momentum margin, and belongs to the field of control distribution. The multi-objective optimization distribution method based on the angular momentum margin is designed for solving the problem that due to the fact that a traditional moment distribution method takes no account of self angular momentum of flywheels, the flywheels are saturated and cannot complete tasks. A weight coefficient optimization method is used, system energy consumption and output margins of the flywheels are integrally considered, a suitable weight coefficient is given to each item according to energy consumption and the output margin of each flywheel, the weight coefficients are adjusted in the process of moment distribution, therefore, energy consumption is reduced, and saturation of the flywheels is avoided. The single-shaft batch counteractive flywheel moment optimal distribution method based on the angular momentum margin is beneficial to improving flywheel system output capacity, can save fuel to a certain extent, and can be widely used for the field of rapid spacecraft attitude maneuver.

Description

technical field [0001] The invention relates to a moment distribution method of a flywheel, in particular to a moment optimization method of a uniaxial reaction flywheel based on an angular momentum margin. In the field of control assignment. Background technique [0002] With the rapid development of my country's aerospace industry, the rapid attitude maneuver and reliability of spacecraft have become the main research content at present. At the same time, fault tolerance plays a vital role in the military field and space applications. For these applications with extreme environments and harsh conditions, the reliability of spacecraft is a key issue that cannot be ignored. Considering the long application period of the spacecraft, the spacecraft is often equipped with a reaction flywheel that only consumes electric energy as the actuator of the attitude control system. At the same time, in order to improve the reliability and output capability of the spacecraft, the react...
