Abstract Details

2003, MS, University of Cincinnati, Engineering : Aerospace Engineering.
In this thesis, the coupled, six-degree-of-freedom, motion equations for a fighter-type aircraft are derived and linearized for a typical subsonic cruise condition involving a coordinated turn at a steady turn rate. Because of the nonzero turn rate and the nonzero roll angle required for it, the equations of motion are coupled and therefore cannot be treated as decoupled longitudinal and lateral motions, particularly for relatively large turn rates. The linearized, coupled motion equations are then used to design a robust linear feedback controller for a particular turn rate using the LQG/LTR design technique. The robust controller is applied to the dynamics at other, considerably different turn rates, demonstrating its robustness. Although a sufficient condition for robust stability is violated over part of the frequency range, less conservative analysis of the closed loop system using structured singular value shows that the controller-plant system is robust to operating point changes.
