This thesis examines the feasibility and a method of extending continuous domain Quantitative Feedback Theory QFT flight control system designs to the discrete domain. The results of two previous QFT analog design efforts are modified for a digital implementation. The first design effort is for the KC-135 transport aircraft. Robust analog fixed compensators are designed for three different flight conditions. The second design effort is for the AFTIF-16 aircraft. In this design, parameter variation is due to both varying flight conditions and different aircraft configurations caused by failed surfaces. Keywords Multivariable control.
