0905 A study on feedback control system of flow separation for windmill by using DBD plasma actuator and FBG sensor

Abstract

A feasibility study of feedback control for mitigating periodic flow separation on NACA0024 airfoil was constructed by using dielectric barrier discharge plasma actuator(DBD-PA) and fiber Bragg grating flow sensor(FBG-FS).Towards applying these devices to small wind turbines,transmission of Bragg wavelengths detected by FBG-FS are tested by using a fiber optic rotary joint(FORJ) from rotor to stationary location Non-contact power transmissions for driving DBD-PAs were also tried by using opposed ferrite pot-cores from stationary location to rotor adversely.
