SUPPRESSION OF WING ROCK OF SLENDER DELTA-WINGS USING A SINGLE NEURONCONTROLLER

Wing rock is a highly nonlinear phenomenon in which the aircraft under goes limit cycle roll oscillations at high angles of attack, A single neuron control scheme for suppression of wing rock of slender delta wi ngs is presented. The effectiveness of the control scheme is demonstra ted through software simulation and real-time control experiments in a wind tunnel on a 80 degrees swept back, wing, The suppression of the limit cycle is achieved in presence of control saturation, The robustn ess of the scheme is demonstrated by the suppression of the wing rock at various initial conditions and different angles of attack.
