Anti-disturbance tolerant control of attitude control systems for satellite based on output feedback control

This paper concerns the reaction wheel failure and system with partial unmeasurable states for the attitude control system of microsatellites. An anti-disturbance tolerant control method based on output feedback control is presented. Due to the disturbance of flexible component vibration and failure of reaction wheel, an disturbance observer based on output feedback control is proposed firstly. Furthermore, the anti-disturbance tolerant control method based on output feedback control is under the condition of fault and disturbance. The controller can be easily solved via convex optimization based on linear matrix inequality. Finally, the simulation results demonstrate that the method proposed is effective.
