Fault Identification and Design of Fault Tolerant Control for a Certain Aircraft

It is critical and important to enhance the service life of aircraft and ensure that aircraft can fly efficiently and safely during the service period. However most of the current research methods are to make fault identification and fault-tolerant control separately. An observer is designed to decouple the external disturbances and actuator faults, and then the fault parameters are estimated. Finally, a controller is designed according to the estimated parameters to ensure the stability of the system. The experimental results show that although there is a steady-state error of parameter tracking in the case of multiple actuator failures, the amended result still can reflect the correct fault parameters.
