This thesis extends previous work on autonomous agile aircraft to develop a framework for control in both linear and non-linear flight profiles. Two dynamical systems are considered, a scale YAK-54 aerobatic remote control aircraft and the Flexrotor concept developed by Aerovel. Both models are capable of hover and level flight, requiring complex control transitions between the flight regimes. Linear controllers are developed for both models in a hover configuration. Open-loop control sequences for the transitions from hover to level flight and back are discussed. All controllers are optimized, and robustness considered additionally, a procedure for providing near optimal non-linear control sequences is proposed. Finally, a general framework for generating control laws of agile aircraft systems is put forth. Simulation results are shown to support the theoretical analysis.
