For example, in this embodiment, the rotary driving device may be selected as the control driving device, so that the movement parameters of the other driving devices are adjusted to the set quantitative parameters. Wherein, the controllable interval of the movement parameter F of the rotary driving device is set, namely, the rotation angle range is [ a, b ], wherein a is the initial angle, and b is the maximum rotation angle.
Halving the controllable interval, i.e., f= (b-a)/2+a, according to the halving principle; and detecting the wind speed Fv of the wind gap corresponding to the F at the moment, and judging whether the FV meets a preset standard or not.
