Review on Fault Detection and Fault Tolerant Control Applied to Flight

Jasim Abdul Huq, Laila Beebi M.

Abstract: In the field of fault analysis of various systems, the fault design comprises of mainly two research streams, one is called fault detection and isolation (FDI) which deals with the detection and diagnosis of faults that occur in a controlled system, and the other called fault tolerant control (FTC) that looks at the task of achieving control for countering the fault. The high complexity of modern systems makes them vulnerable to almost any fault such as sudden breakdown or malfunction of a sensor or an actuator. Therefore, in order to improve the operational safety and system redundancy, reducing the possibility of such failures or predicting it before its occurrence is imperative. This review paper presents different fault detection and control strategies involved in flight.
