This thesis concerns the design, analysis and testing of adaptive controllers for rotary wing
aircraft, in particular helicopters. A non-linear helicopter model is developed and validated by
trim and dynamic response analyses. A inner-outer loop cascade controller is designed with
a trajectory generator in the most outer layer and an adaptive neural network controller is
implemented to the inner loop. Controller is then challenged to carry out complex maneuvers
autonomously under turbulence. Finally, the center of gravity location is varied to severe
values to observe adaptation characteristics to investigate the requirement on the knowledge
of the center of gravity location during such adaptive controller design.
