Abstract :
The robust Fault-Tolerant H∞ Control problem of uncertain linear system is studied in this paper. It is shown that a solution of this problem can be obtained from a system of a linear matrix inequality (LMI). This method possesses integrity against sensors and actuators faults, have robustness to parameter uncertainty and satisfy disturbance attenuation index. At last, the simulation of a satellite attitude control system with actuator and sensor faults validates that this solution is effective and more suitable in on-board real-time computation.
