Abstract
A control method for an unmanned aerial vehicle (UAV) is provided. The UAV includes an accelerometer, a gyroscope, at least one drive unit and at least one rotor. The method includes: detecting current motion data from the accelerometer, wherein the motion data includes displacement of the UAV; determining whether the UAV is thrown up based on the motion data; detecting current ascending velocity of the UAV; determining whether the current ascending velocity of the UAV is substantially equal to zero; detecting current pitch angle and current angular velocity from the gyroscope if the current ascending velocity of the UAV is substantially equal to zero; calculating drive data based on the current pitch angle and current angular velocity; and enabling the at least one drive unit to drive at least one rotor to rotate so as to cause the UAV to hover evenly.
