| Abstract: | This paper focuses mainly on the mathematical model of ground target tracking of a video satellite and the design of an attitude tracking controller.Firstly,the desired attitude quaternion and the desired attitude angular velocity are presented respectively according to the orbit kinematic and attitude kinematic.Then,a feedback PD controller based on the error quaternion and error attitude angular velocity is designed,and the stability of the designed controller is analyzed by using the Lyapunov stability t... |
