Abstract:

An integrity fault tolerant control problem of uncertain linear system is studied. Based on the Riccati equation and linear matrix inequality, an integrity fault tolerant attitude controller with disturbance attenuation is designed for the actuator failure of the satellite by using four reaction wheels. Furthermore, the conclusion that the designed controller  can be applied to more kinds of actuator failure forms can be drawn. The simulation on the satellite attitude system demonstrates the correctness and effectiveness of the proposed method.
