摘　　要：采用模糊逻辑控制器与LQR相结合的控制策略来解决自主运行卫星编队构形重构问题。首先,基于Hill方程,利用LQR理论设计控制器;然后,设计模糊逻辑控制器,利用编队运行中的导航信息、通信信息以及任务优先级信息,对控制器增益进行模糊调节。该控制策略可以有效实现编队构形重构,且能在燃料消耗量与任务优先级和构形差异之间达到折衷。仿真结果表明了方法的有效性。A hybrid control strategy of fuzzy logic control and LQR is adopted for autonomous satellite formation reconfiguration. Based on Hill＇s equation, a linear quadratic optimal controller was developed to accomplish the reconfiguration. Then a fuzzy logic controller was designed as a regulator to modify the optimal control gains based on the run-time information, including navigation, communication, mission priority, and so on. The control strategy is efficient in satellite formation reconfiguration, and can make tradeoff between mission priority, configuration error and fuel consumption. Simulation results show the validity of the scheme.
