摘　　要：基于Newton-Euler法建立了绳系太阳能发电卫星受重力梯度影响的动力学模型.在考虑常值扰动力矩的影响下,设计了线性二次型调节器和自适应估计器相结合的姿态稳定控制器,并以反作用飞轮系统作为执行机构实现该控制律.仿真结果验证了该控制方法的有效性.Dynamics of the space solar power satellite with the effect of gravity gradient is derived on basis of Newton - Euler method in this paper. Taking the influence of constant disturbance torque into account, the controller for the attitude stability of satellite is designed, which is Composed of a linear quadrics regulator and an adaptive estimator. The flywheels are selected as the actuators to generate the control torque. Simulation verifies the validity of the designed control law.
