五、中期答辩内容简介：
For autonomous systems, real time fault detection in components is vital to avoid potential loss of life and property. Moreover, control actions to quickly mitigate the effects of faults must be ensured. In this work, we have concentrated on the development of single unified framework for real time fault detection, isolation, and estimation. The fault signals provide good real time fault estimates to be used in fault tolerant control. To avoid the problems associated with control reconfiguration, active control strategies are developed using sliding mode control such that the same controller works in both faulty and fault free conditions. We have addressed the issues such as time delay and overshoots in fault estimation using novel methods to train the neural networks used in the fault estimations scheme. The developed methods are successfully applied to aircraft sensors and actuators fault diagnosis and fault tolerant control.
