The invention discloses a variable-frequency oscillation jet device based on flow control and a control method thereof, and belongs to the field of aircraft flow control. Synthetic jet is selected to replace a feedback channel of a traditional oscillation jet device, so that the variable-frequency oscillation jet device can realize different oscillation frequencies at the same flow speed; the oscillation frequency and speed of the oscillation jet device can be decoupled in flow control; the oscillation characteristic of synthetic jet is combined with the variable-frequency oscillation jet device, so that the oscillation frequency, speed and size of the variable-frequency oscillation jet device are decoupled, and different oscillation frequencies are controlled under the same momentum coefficient in flow control, so that the lift augmentation effect of the oscillation jet device is optimal in the flow control.
