Abstract Details

2016, MS, University of Cincinnati, Engineering and Applied Science: Aerospace Engineering.
The purpose of a flight control system is to provide stability and control for the aircraft with the help of control surfaces. FCS helps improve aircraft performance characteristics during flight. Stability is secured by the mechanism of feedback. Feedback plays an important part in providing a baseline control approach for stabilizing a non-linear unstable aircraft. It helps suppress effects of disturbances. Numerical Linearization is used to design a stabilizing controller for a non-linear model of the F-16 Fighting Falcon jet initialized with nominal flight condition. First a single-loop at a time feedback is designed using Matlab for longitudinal stabilization. Then the lateral modes of the aircraft are fed back and used in a single-loop at a time fashion to stabilize the lateral dynamics. Then, a multivariable feedback approach is used to stabilize the lateral dynamics for a constant turn rate condition using a cost function optimization approach to find suitable gains for the feedback loops. All of these controllers are tested by using a non-linear Simulink simulation of the scale-model F-16 dynamics
