| Abstract: | 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. |
