L1 adaptive control augmentation system for the X-48B Aircraft

This thesis considers the application of L1 adaptive control methodology to a model of the X-48B Blended Wing Body aircraft. We explicitly verify the performance bounds of the adaptive flight control system at various flight conditions. We demonstrate that the resulting L1 adaptive controller does not require tuning or redesign from one flight condition to another. Furthermore, once designed according to the theoretical guidelines, the L1 adaptive controller ensures uniform transient and steady-state performance across the entire flight envelope in the presence of significantly coupled dynamics and control surface failures.
