Fault tolerant control system design by using adaptive observer, case study: Civilian aircraft

Abstract

In this paper, a continuous fault tolerant controller with uniform HOSM observer for identification and isolation of error in a model dynamic system is proposed. This fault-tolerant controller is based on integral sliding mode that is based on CA. According to the explanations provided, in the presence of uncertainties and actuator faults, stability of closed loop system by using this controller is checked and proved along with convergence of output to the reference signal. This control model was used on a passenger plane Boeing B747 in the simulation and the results indicate the effectiveness of the system.
