N2 - Retrospective cost adaptive control is applied to low Reynolds number aerodynamics around an SD7003 airfoil with a dielectric barrier discharge (DBD) actuator located near the leading edge. The adaptive control algorithm uses knowledge of Markov parameters to capture information about any nonminimum-phase zeros in the dynamics. In this paper, we explore the impact of the adaptive controller on the aerodynamics under the chord Reynolds numbers of 300 and 60,000, and with both steady and unsteady free-stream conditions. By varying the voltage to the DBD actuator, effective control of unsteady flow structure can be performed to decrease drag and increase lift.
