The design of the high-precision attitude control system of the LEO

This paper designs the H_∞ state feedback controller of the low-orbit satellite to achieve the high precision attitude control. Based on the analysis of the system uncertainty and environment disturbance of the low-orbit satellite, H_∞ method is adopted and the LMI arithmetic is used to make the computation easier. The results of the system simulation prove that the algorithm is useful and can make the attitude control system achieve the high precision requirements.
