摘要
针对临界比例度法,继电反馈法在获取振荡周期和对应增益上的问题,提出一种PID参数整定频域分析方法,试验结果表明该方法在低频可得到较好的频率特性。
Aiming at problem of getting vibrating period and amplitude in critical scaling limited method and relaytuning method, a frequency domain analyse method of PID control system is referred. The experiment results show it has good frequency characteristic in low frequency.
