摘要
力矩平衡姿态的稳定性是空间站姿态TEA定向控制研究的重要问题。采用Lyapunov理论中求解导算子特征值的方法判断TEA的稳定性,基于线性化的姿态动力学方程采用基于稳定度设计的LQR方法设计空间站的姿态控制器,通过仿真验证了:(1)TEA作为平衡姿态的优点;(2)用导算子的特征值判断TEA姿态稳定性的方法的有效性。
The stability of TEA is a very important problem in the space station TEA maintaining control study. The Lyapunov theory is used to judge the stability of TEA by calculating all the characteristic vectors and eigenvalues of the differential operator, and the stability based LQR controller for space station attitude control is developed based on the linearized attitude dynamic equations. The simulation results prove： （1） the advantages of TEA as a balanced attitude; （2） the effectiveness of the stability judge method of calculating all the characteristic vectors and eigenvalues of the differential operator.
