This paper concerns the complete loss of reaction wheel effectiveness problem for the attitude control system of microsatellites. An anti-disturbance tolerant control method with disturbance rejection and compensation is presented. Due to the complete loss of reaction wheel effectiveness, four reaction wheels are applied for attitude control, which not only considering the external environment disturbance...
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,...
