Adaptive synthetic jet actuator compensation for a nonlinear tailless aircraft model at low angles of attack

In this paper, we develop an adaptive compensation scheme for aerodynamic flow control of synthetic jet actuator arrays on a nonlinear tailless aircraft model at low angles of attack. Adaptive inverse is employed for cancelling the effect of the jet nonlinearities. A nonlinear state feedback control law is designed for controlling the aircraft dynamics, wherein a set of intermediate states are used as control signals for other states of the aircraft. A meaningful allocation of control signals is also proposed. Parameter projection based adaptive laws are used to ensure desired closed-loop stability and asymptotic tracking
