摘要: 为了获得使人感到舒适的自然风,提出了对风扇转速进行1/f控制的方案,详细论述了1/f波动数据的生成和对风扇电机电压的控制方法,并用单因素方差分析的方法将1/f波动控制产生的舒适感的效果与白噪和1/f2波动控制方式的情况进行比较,证明了1/f波动控制方式对于提高人的舒适感的有效性.Abstract: In order to get comfortable and natural wind, a method which make power spectrum of wind-s velocity conforms to 1/f fluctuation is mentioned. Data conforming to 1/f fluctuation by using 1/f fluctuation filter controlled the velocity of motor using a booster. By the comparison among feelings got by wind of the 1/f fluctuation, that of the 1/f2 fluctuation and that of the white noise fluctuation using variance analysis, a conclusion is drawn that humans- feeling of comfort is implemented efficiently by 1/f fluctuation controlled electric fan.
