This paper investigates the problem of attitude fault tolerant control (FTC) for satellites subject to multiple disturbances and actuator faults. Due to the limitation of the physical characteristic, actuator saturation exists quite widely in practical processes. An anti-windup FTC approach based on disturbance observer is presented for satellites with actuator faults, input saturation and multiple...
In this paper, an adaptive fault tolerant control (FTC) method based on disturbance observer is proposed for microsatellite attitude control system (ACS) with actuator faults and multiple disturbances simultaneously. Disturbance observer and fault diagnosis observer are designed to estimate the modeled disturbances and faults of flywheels, respectively. An adaptive term is applied to compensate norm-bounded...
