Abstract:

At high angles-of-attack AOA flow separations can produce non-linear and time varying aerodynamic loads, which cannot be predicted with great certainty. Such loads make control system development extremely difficult. A control system has thus been developed which can accomplish on-line reduction of the a-priori uncertainties pertaining to the effective control of the aircraft. The self-organising control system was developed to suppress unacceptable pitch-up tendencies of an aircraft at high AOA, without the use of AOA measurement. The final control system demonstrated good performance for a variety of inputs although performance was not as good in turbulence.
