针对含混合执行机构的姿态控制系统中常见构型配置问题进行研究,选择金字塔(PC)、五棱锥安装(FPC)的单框架控制力矩陀螺群(SGCMG)与三正一斜装、四斜装的动量轮(MW)分别进行执行机构组合构型比较。根据提出的构型评价指标,考虑各组合构型因故障进行重构情形,从角动量包络、执行机构功耗、系统控制性能、构型安装位置等方面研究卫星混合执行机构的可重构性。通过对各混合构型及其重构构型完成姿态大角度机动进行仿真,得到相关可重构性研究结论,结果表明混合执行机构的可重构性与构型安装数目及位置有着密切的关系,执行机构功耗也影响其可重构能力等,可以为卫星混合执行机构可重构性评价和设计提供相关参考。
Aiming at the problems of common configurations in the attitude control system with hybrid actuator, this paper selects the single-frame control moment gyroscope group (SGCMG) with pyramid (PC) and pentagonal cone mounting (FPC) Of the momentum wheel (MW), respectively, the actuator combination configuration comparison. According to the proposed configuration evaluation index, the reconfiguration of the hybrid hybrid actuator based on the angular momentum envelope, the actuator power consumption, the system control performance, and the configuration of the hybrid actuator is considered Sex. Through the simulation of each hybrid configuration and its reconfiguration configuration to complete the attitude large-angle maneuver, the conclusion about the reconfigurability is obtained. The results show that the reconfigurability of the hybrid actuator is closely related to the number and location of the configuration installation , The power consumption of actuators also affects their reconfigurability, etc., which can provide reference for the reconfigurability evaluation and design of hybrid hybrid actuators.
