摘要: 研究了一种无角速度信息挠性航天器的姿态稳定控制方法。针对挠性航天器陀螺故障或无陀螺配置情形下无角速度测量信息的姿态控制问题,基于姿态四元数设计了姿态定点调节的无速率控制器,利用Lyapunov方法和LaSalle不变原理证明了闭环系统的全局渐近稳定性,并对控制方案进行了改进。仿真验证了控制律的有效性。

Abstract: A method for designing attitude stabilization controllers is proposed in this paper for flexible spacecraft without angular velocity measurements. In order to solve the attitude control problem when the angular velocity is not available due to gyro failure or gyroless configuration, a velocity-free attitude regulation controller is proposed in this paper based on quaternion with the global asymptotic stability of the closed loop system proved by combining the Lyapunov direct method with the LaSalle’s theorem. An improved controller is also designed in this paper. Numerical simulations demonstrate the effectiveness of the proposed method.

Key words: flexible spacecraft, attitude control, velocity-free controller, Lyapunov approach
