Abstract:
The robust fault-tolerant H-infinity control problem of uncertain linear system is studied in this paper. The solution of this problem is obtained for a H-infinity output feedack controller by a linear matrix inequality （LMI） approach. 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.[著者文摘]
