摘　　要：针对太阳帆航天器行星悬浮轨道保持控制问题进行了研究.首先,建立了柱坐标系下太阳帆动力学模型;然后,对模型进行线性化处理,推导出太阳帆状态方程;接着,设计线性二次型调节器(LQR)及基于遗传算法(GA)改进的控制器,对出现扰动的轨道进行控制;最后,通过仿真结果对比,表明上述控制器均可实现轨道保持控制,且基于GA改进的LQR性能明显优于传统LQR.The problem of maintaining control of the planetary suspension orbit of the solar sail spacecraft is studied.Firstly,the solar sail dynamics model is established under the cylindrical coordinate system.Secondly,considering the positional disturbance existing in the orbit,the model is linearized to derive the solar sail state equation.Then,the linear quadratic regulator(LQR)is designed.And the improved controller based on genetic algorithm(GA)controls the disturbed orbits.Finally,the simulation results show that the above controllers can achieve track-holding control,and the improved LQR performance based on GA is significantly better than the traditional LQR.
