In flight control systems it is crucial to accommodate actuator failures for safe operation. Modern flight control systems are equipped with multiple power sources and actuation systems that offer redundancy in the event of actuator failures. Traditional approaches to flight control system design involve scheduling of fixed gain controllers and control allocation to take full advantage of redundant actuators. Alternative adaptive control approaches have been extensively investigated recently to provide enhanced fault tolerance by augmenting an existing flight control design with adaptive elements. This paper provides a brief background of the state of the art in adaptive fault tolerant flight control and presents a comparison study of several novel direct neural network based adaptive control methods. © 2008 by the American Institute of Aeronautics and Astronautics, Inc.

A Model Based Approach for Sensor Fault Detection in Civil Aircraft Control Surface Sercekman, O.; Kutay, Ali Türker (2018-04-26) A model-based fault detection and diagnosis (FDD) solution improves the capability in a civil aircraft control surface whereas having low complexity and computational requirements. The main objective of the FDD. techniques that are extensively applied in industrial systems is to increase the sensitivity of fault detection scheme while maintaining a reliable system response with respect to additional unknown inputs. In the paper, a reformative approach to an observer-based fault detection method is introduce...
A model - based jamming detection method for electro-hydrostatic actuators Poyraz, Emre Murat; Turgut, Ali Emre; Çalışkan, Hakan (2020-09-01) An anomaly or a fault, which may be treated as insignificant in a complicated engineering system, like an electro–hydraulic flight control actuator, can cause considerable performance degradation and deteriorating effects or even worse it may end up with a catastrophic system failure. One of the problems commonly observed in air vehicles is called jamming. Jamming is the type of failure where an actuator connected to a flight control surface permanently gets stuck at a certain position and does not move any...
A Model based approach for aircraft sensor fault detection Serçekman, Ömür; Kutay, Ali Türker; Department of Aerospace Engineering (2018) This thesis presents a reformative approach to a model-based fault detection and diagnosis (FDD) method that improves the capability of aircraft flight control systems and acquires low complexity and computational requirements. The main objective of the FDD techniques that are extensively applied in industrial systems is to increase the sensitivity of fault detection scheme with respect to additional noise, uncertainty or disturbances. The designed fault detection model is integrated to a civil aircraft mod...
A closed-loop flight control experiment using active flow control actuators Kutay, Ali Türker; Muse, Jonathan A.; Brzozowski, Daniel P.; Glezer, Ari; Calise, Anthony J. (2007-07-02) Closed-loop pitch control on a moving 1-DOF wing model is investigated in wind tunnel experiments. The model's attitude is controlled over a broad range of angles of attack when the baseline flow is fully attached using bi-directional pitching moment that is effected by flow-controlled trapped vorticity concentrations on the pressure and suction surfaces near the trailing edge. In the present work, the model is trimmed using a position feedback loop and a servomotor actuator. Once the model is trimmed, the ...
A Functional design methodology with genetic algorithm optimization to a door actuation mechanism Akman, Hasan; Turgut, Ali Emre; Department of Mechanical Engineering (2019) In this thesis, the preliminary design of an in-flight refueling door actuation mechanism is designed. A novel design methodology is introduced to create and evaluate different mechanism design alternatives systematically. The design is divided into two sub-problems. For each sub-problem, different conceptual design alternatives and evaluation criteria are created considering the design requirements. Suitable concepts are systematically selected among the alternatives based on the evaluation criteria. Then,...
