| 摘 要： | 挠性航天器在姿态机动过程会受环境干扰力矩的作用,研究有扰情况下挠性航天器的姿态跟踪控制问题.首先,设计了干扰观测器在线估计频率已知的外部干扰信号,然后,基于干扰观测器设计了非线性反馈姿态跟踪控制器以跟踪目标姿态,并且该控制器只需要误差四元数和角速度的反馈信息.其次,采用Lyapunov方程和Barbalat引理证明了控...

| Abstract: | The problem of tracking a desired attitude is here addressed in the case of a flexible spacecraft subject to environmental disturbances.Firstly,a disturbance estimator is developed to estimate external disturbances with known frequencies.Based on the estimator,a nonlinear feedback attitude tracking controller is constructed to track a desired attitude,which only needs error quaternion and angular velocity measurements.Then,The Barbalat lemma and Lyapunov function are adopted to prove the global stability of... |
