Abstract :
This paper proposes a new discrete-time fault estimation scheme that deals with multiple, simultaneous and abrupt actuator failures. The proposed actuator fault estimation scheme is applied to design a fault-tolerant H∞ flight controller for a combat aircraft in tracking bank-angle and pitch-rate commands with zero lateral acceleration. Simulation results demonstrate good performance using the fault-tolerant H∞ flight controller.
