Abstract :
The controller design of the drag-free satellite on near-earth orbit is the researching object. After analyzing the characteristics of the main disturbances affecting the drag-free satellite, the disturbance model is established. Adding the disturbance to the system, a disturbance observed based dynamics model of the drag-free satellite is built. Then the mixed H2/H∞ controller is designed and the LMI form is given to solve it. Simulation results verify the stability and feasibility of the controller.
