This work develops a systematic design procedure for flight control laws design which allows: the use of best practices; compatibility with current fly-by-wire implementation; and integration with aircraft and systems design. Such procedure is based on a two-degree-of-freedom control structure, the first degree of freedom defining input to output characteristics and the second coping with disturbance rejection, noise rejection and robustness. The procedure uses a frequency domain based uncertainty description for treating robustness. A case study comprising a primary longitudinal flight control law design for a business aircraft is defined to evaluate the procedure. Results show the adequacy of the procedure: to coalesce many different requirements into simpler ones; evidence compromises between different requirements; design robust control laws given a set of reasonable requirements.
