Four different multivariable model-following design techniques were evaluated to assess their applicability to the flight control law design of advanced aerospace vehicles. The ability of these synthesis techniques to meet the flying qualities, robustness, and turbulence rejection requirements of future fighter aircraft within the deflection and rate constraints of the actuation system was examined. The gain scheduling required to implement the control laws developed by these synthesis techniques was also investigated and the manpower required to formulate a control system capable of meeting the chosen design objectives was evaluated. This evaluation identified strengths and weaknesses of the techniques and established effective ways of applying these algorithms to the design of 'real world' high order control systems. It was determined that these algorithms can meet flying qualities requirements for advanced fighter aircraft while satisfying stability margin and turbulence rejection requirements. However, the ability of these algorithms to effectively manage high order dynamics such as actuator dynamics, sensor dynamics and structural filters should be improved.
