针对卫星姿控系统执行机构可重构性设计,提出了可重构性评价指标,并以推力器为具体的执行机构建立了优化设计模型,将遗传算法应用于其最优解的求取。Matlab/Simulink环境下搭建的卫星闭环姿控系统仿真结果表明,设计安装方案无论在故障情况下还是在正常情况下,系统可重构性和控制性能均明显优于其他比较方案,在一定程度上有效地验证了所提优化设计方法和结果的合理性和正确性。
Aiming at the reconfigurable design of actuator for satellite attitude control system, the reconfigurable evaluation index is put forward and the optimal design model is established by using thruster as actuator. The genetic algorithm is applied to the optimal solution. The simulation results of the satellite closed-loop attitude control system built under the Matlab / Simulink environment show that the system reconfiguration and control performance are obviously superior to other comparison schemes in the case of fault or under normal conditions, to a certain extent Which effectively validates the rationality and correctness of the optimized design methods and results.
