A new control problem associated with a periodic time-varying system(PTS), arises in the control of unsteady flow over a blade as the wind turbine rotating. The model of the plant is considered as an aeroelastic pitch-plunge system coupling with B-L model and the stability of the system is analyzed by well-know floquet theory. Adaptive Control is adopted to overcome the fluctuation brought by periodic fluctuations of the flow. A modified PTS adaptive control stability theory is given and proved for linearized aeroelastic plant. The effectiveness of the proposed theory is demonstrated numerically.
