Description

technical field [0001] The invention relates to an optimization method for reaction wheel underactuation configuration, which belongs to the technical field of aerospace control. Background technique [0002] The reaction wheel is a commonly used actuator in the spacecraft control system, and it is of great engineering significance to study the underactuated configuration optimization of the reaction wheel. On the one hand, optimizing the underactuation configuration of the reaction wheel can effectively improve the autonomous operation capability of the spacecraft, and can still ensure the normal operation of the spacecraft in the event of a failure. On the other hand, it can also effectively save the design of the spacecraft control system. Cost, the underactuation is specially used for control in the design of the spacecraft control system. [0003] At present, the research on the configuration optimization of reaction wheels for underactuated conditions is relatively la...
