摘要
建立了卫星编队飞行的相对姿态动力学和运动学模型。利用积分反步法,设计了能够保证控制系统稳定性的控制器和角速度观测器,使得卫星编队飞行控制系统在不安装星载角速度测量设备的情况下仍能保持对理想相对姿态的跟踪,利用Lyapunov稳定性理论证明了系统的指数稳定性。
The dynamics and kinematics of the relative attitude of satellite formation flight are derived. According to the integrator backstepping method,a controller and an angular velocity observer are designed. Based on the observer,the control system can keep tracking the desired relative attitude without the angular velocity measurements. The exponent stability of the closed-loop system is proved by using the Lyapunov stability theory.
