The control problem of underactuated spacecraft chaotic attitude motion is investigated based on exponential reaching law in this paper. First, the underactuated spacecraft chaotic attitude system is written in nonlinear equation form with two controls. Once the trajectory planning of angular acceleration is preset, the dynamics equation of angular velocity error can be obtained. Then, the sliding...
After rendezvous and docking, the mass and mass center of target satellite can change greatly. In order to identify the mass and mass center of target satellite, research is made about the identification of mass and mass center about target satellite. As to the mass of target satellite, according to the information when the tracking satellite is located in different relatively stable position with...
After capturing the tracking satellite, the target satellite will turn into a compound satellite, and the inertia parameters of target satellite can produce great changes and greatly affect the attitude control system and its control effect. In order to estimate the inertia parameters of target satellite, two methods including the method based on Angular Momentum Conservation Law and the modified...
