Design & analysis of self repairing controllers to compensate actuator failures in aerospace systems

My research proposes new autopilot design for safety critical systems such as large civil aircraft ensuring no casualties in the event of unanticipated uncertain control surface or engine failures unknown in time pattern and magnitude, within the framework of adaptive control. This technology after further developments will be extremely useful for the crew onboard to ensure a safe flight even in the case of such actuator failures. In my research, I have proposed decentralized adaptive schemes for longitudinal control of Boeing 747-100/200. This would be very much useful in the context of industrial relevance for example, taking into consideration the recent engine failures encountered by Jet Airways while take off. Fortunately, a catastrophic accident was avoided with the expertise of the pilots on board. The proposed schemes would prove to be valuable in guaranteeing acceptable output transient performance and flight safety with minimum intervention of the pilot in cases of unknown actuator failures. Hence, safety critical missions can be successfully accomplished.
