Özet

Some faults which occur in automatic flight control systems can affect the control of the aircraft. By means of automatic flight systems, control movements can be given in the sensitivity that pilots can not be able to give. Hence, some faults which occur on sensor, actuator and control surface should be controlled by some controllers. Filters, observers, parameter estimation systems, parity equations and signal models are used for this purpose. The basic principle of observers is the state variables which predicted by observers of another system converge to the state variables of a dynamic system. In this study, full-order observer and Generalized Observer Scheme (GOS) were used to detect and isolate aircraft sensor faults in an aircraft lateral flight control system. While fullorder observer is used for sensor fault detection, GOS is used for sensor fault isolation. Full-order observer and GOS were designed using MATLAB software to detect and isolate aircraft sensor faults in an aircraft lateral flight control system.
