This thesis demonstrates the design of a lateral flight controller for the C-135 aircraft using the frequency response approach of Professor Izaac Horowitz, University of Colorado, Boulder, Colorado. A single controller is designed for the entire flight envelope of the aircraft, from high speed, high altitude cruise to a low altitude approach condition. A three degree-of-freedom lateral model is reduced to a two degree-of-freedom model. The equations of motion assume a linearized aircraft model operating around equilibrium flight conditions allowing only small perturbations from equilibrium. Robustness of the design is guaranteed, since the variation in flight parameters is considered throughout the entire design process. Robustness is demonstrated by simulating the compensated aircraft at the extremes of the flight envelope considered. This thesis concludes that the approach of Professor Horowitz is useful for the design of flight controllers for the C-135 aircraft. Some software development to aid in the design process is recommended. (Author)
