摘要
研究了控制力矩受限时空间飞行器的大角度姿态机动控制问题。为克服大角度机动时使用欧拉角可能产生的奇异问题,文中使用四元数形式的微分方程来描述飞行器的运动。首先运用Lyapunov方法,然后根据能量重置耗散思想,基于非线性脉冲混杂系统的扩展La-Salle不变集原理,设计了混杂脉冲大角度调节器。仿真结果表明:控制算法能在输入力矩有限的条件下较快地实现姿态大角度机动,具有设计简单、易于工程实现的特点。
The large angle attitude maneuver control of spacecraft with bounded inputs is investigated. To remove the singularity due to the use of Euler angle in large angle attitude maneuver,the kinematics of the spacecraft is described by quaternion. Using Lyapunov theory,and motivated by the recent results on invariant set stability theorems of nonlinear impulsive hybrid systems,a class of large angle attitude maneuver hybrid dynamical controller with bounded inputs is derived. Theoretical analysis and simulation results indicate that the proposed control algorithm has excellent dynamic performance and can be easily designed and realized.
