phase-frequency response
phase-frequencyresponse

Dynamic characteristic of the fan system was tested in this paper . the time constants of acceleration and deceleration was gotten and bode diagram of frequency response was presented . the results show that the frequency response of the system is satisfying in the range up to 0 . 2 hz
本文对风机系统的动态特性进行了测试，得到了它的加减速时间，并通过谱分析法得到了系统的幅相频响应曲线( bode图) ，结果表明系统在低于0 . 2赫兹范围有较好的相应特性。
