• Pitch and flight path control with simultaneous forward gust rejection 

      Skarpetis, M. G.; Koumboulis, F. N.; Koussiouris, T. G. (1999)
      The problem of rejecting atmospheric disturbances with simultaneous input-output decoupling of the pitch angle and the flight path angle of an aircraft, is studied. The problem is proven to be solvable for almost all flight ...
    • Robust Morgan's problem 

      Koumboulis, F. N.; Koussiouris, T. G.; Skarpetis, M. G. (2004)
      The robust Morgan's problem, via restricted static state feedback and a constant precompensator, is studied for nonsquare linear time-invariant systems with nonlinear uncertain structure. Sufficient solvability conditions ...
