Abstract EN
The antidisturbance fault tolerant control problem of attitude control systems for microsatellite is investigated in the presence of unknown input delay, stuck faults from the reaction wheel and the multiple disturbances.
The multiple disturbances are supposed to include the vibration disturbance torque from the reaction wheel and modeling uncertainties.
The fault diagnosis observer and disturbance observer are constructed to estimate stuck faults and vibration disturbance torque from the reaction wheel, respectively.
A composite fault tolerant controller is designed by combining a PID controller, the fault accommodation estimation based on the fault diagnosis observer, and the disturbance compensator based on the disturbance observer.
The controller and observer gains can be easily obtained via a set of linear matrix inequalities.
Simulation results are given to show that the faults can be accommodated readily, and the disturbances can be rejected and attenuated simultaneously.
