The invention discloses an underwater glider closed-loop active flow control device based on synthetic jet, and relates to the field of active flow control. The underwater glider closed-loop active flow control device comprises a piezoelectric film vibration type synthetic jet exciter arranged at the rear end in an underwater glider wing, and the piezoelectric film vibration type synthetic jet exciter is electrically connected with a control unit and a sensor in sequence; and a plurality of synthetic jet nozzles are formed in the rear end of the upper surface of the underwater glider win, nozzles are formed in the piezoelectric film vibration type synthetic jet exciter, and the nozzles are located at the positions of the synthetic jet nozzles. According to the underwater glider closed-loopactive flow control device based on the synthetic jet, local or global effective flow changes are obtained through local disturbance, and then the purposes of increasing lift, reducing resistance, improving a flow field, restraining noise and the like are achieved.
