Research on torque allocation for multi-reaction wheels system

Zhang Zhongzheng; Li Dongbai; Sun Zhaowei

This article deals with torque allocation for multi-reaction wheel in spacecraft. First of all, an energy-based optimal allocation strategy is derived under the constraints of reaction wheel maximum output torque. Secondly, to address the shortened life time problem which results from too large torque output of some specific reaction wheel in energy-based optimal allocation strategy, the concept of output margin is proposed, and a multi-objective optimal model is put forward. Then, based on weighted coefficients theory an energy-output-margin-based optimal allocation strategy is developed, which can flexibly and effectively solved torque allocation in engineering. Finally, eight skewed reaction wheel system numerical simulation results show the effectiveness of the proposed strategy.
