Measurements of the lift coefficient history obtained from a NACA 0018 airfoil undergoing pitching maneuvers with blowing-type active flow control were used to obtain low-dimensional models for control. Disturbance models for the lift response to pitching at different steady-state blowing amplitudes were identified based on a variation of the Goman–Khrabrov model. A plant model for the lift response to sinusoidal blowing amplitude had the form of a time-delay system. The models were used to design a feed-forward controller. The ability of the controller to compensate for lift oscillations during pitching maneuvers was evaluated using a Simulink® model.
