摘要 研究基于状态相关的Riccati方程(SDRE)方法的挠性航天器姿态控制问题。首先基于挠性航天器的姿态动力学方程,推导了用于姿态跟踪控制器设计的误差动力学方程;然后用SDRE方法对挠性航天器进行了姿态控制器的设计;接着采用了三种方法对SDRE控制器进行求解,即Schur法、改进的Newton法和θ-D法,如果将期望姿态设为某固定姿态,则该控制器实际上成为一个次优姿态机动控制器;最后以某挠性航天器为背景对三种解法进行了数值仿真和比较。仿真结果显示,改进的Newton法计算精度最高,Schur法其次,尽管相比之下θ-D法的计算精度最低,但它也能保证足够的控制精度,而其计算效率是其它两种方法所无法比拟的,θ-D法高效的控制器解算使SDRE的工程应用成为可能。 This paper studies the attitude control problem of flexible spacecraft via state-dependent Riccati equation(SDRE) technique.Firstly,the dynamic equations of a flexible spacecraft are established and the error dynamic equations are derived.An attitude controller is designed via SDRE technique.The controller is solved using three methods,i.e.Schur method,modified Newton method,and θ-D method.The controller will transform into a suboptimal controller on attitude maneuver if the desired attitude is fixed.Finall...
