摘要: 针对目前在控制系统的可重构性评价中较少考虑系统能耗、可靠性限制的问题,文章研究了约束条件下卫星姿态控制系统可重构性度量及评价方法,建立了含执行机构失效因子的控制系统模型,并基于可控性格兰姆矩阵得到能耗约束下可重构性度量指标;然后将可靠性指标引入到系统可重构性评价度量中,进一步缩小可重构性集合;最终形成综合两种约束的可重构性评价方法。通过对含动量轮系统的重构构型仿真,得到约束前后的可重构性对比,仿真结果符合实际分析,验证了该方法的有效性。

Abstract: Since the energy consumption and system reliability constraint was rarely considered in the control system reconfigurability evaluation, the reconfigurability measurement and evaluation method were studied under the constraints for the satellite attitude control system. The control system model including the actuator failure factor was established. Based on the controllability Gramian Matrix, the reconfigurability measurement index under energy consumption was obtained. Furthermore, the control reconfigurability index was introduced into the system reliability constraint, which narrowed the set of reconfigurable systems. Finally, the combined index was obtained. From the control system with momentum wheels simulation, the reconfigurability comparison results among different constraints can be acquired. The results show that this evaluation method is effective.
