Abstract：This paper presents a method of spacecraft reaction wheel actuator configuration based on comprehensive evaluation index, which can be useful in the design of spacecraft control systems. Firstly, based on the functional and hardware requirements of the actuator configuration in the control system, a set of feasible configuration schemes that satisfies the requirements is determined. Reaction wheel is selected as the actuator in this set. In addition,its mounting structure is skewed,with the mounting angle of the structure determined by the actual requirements of the control system and the minimum energy consumption. Secondly,the optimal configuration scheme of the feasible configuration scheme set is determined by the comprehensive evaluation of the characteristics of the actuator configuration. The least squares method is used to optimize the subjective and objective evaluation methods,with the merits of the scheme determined by its proximity to the positive and negative ideal schemes.Finally,the proposed method is applied to the actuator configuration requirements of a spacecraft control system design,with the results showing that the method is feasible and effective and, consequently,has value for engineering applications.
