The purpose of this study was to evaluate the performance and stability robustness of a lateral autopilot designed for a transport aircraft using H2 and HInfinity control theory. The intent was to design a controller that met performance and robustness specifications over a range of flight conditions. First, a control structure to be used in designing the autopilot was developed. Once this was accomplished, it was formulated into the small gain problem. Controllers were then developed using H2 and HInfinity control theory. The final task involved evaluating the controllers developed in a closed loop simulation.
