PID控制器参数的整定步骤如下：

　　(1)首先预选择一个足够短的采样周期让系统工作；

　　(2)仅加入比例控制环节，直到系统对输入的阶跃响应出现临界振荡，记下这时的比例放大系数和临界振荡周期；

　　(3)在一定的控制度下通过公式计算得到PID控制器的参数。

　　PID参数的设定：是靠经验及工艺的熟悉，参考测量值跟踪与设定值曲线，从而调整P\I\D的大小。

　　比例I/微分D=2，具体值可根据仪表定，再调整比例带P，P过头，到达稳定的时间长，P太短，会震荡，永远也打不到设定要求。

　　PID控制器参数的工程整定,各种调节系统中P.I.D参数经验数据以下可参照：

　　温度T：P=20~60%，T=180~600s，D=3-180s；

　　压力P：P=30~70%，T=24~180s；

　　液位L：P=20~80%，T=60~300s；

　　流量L：P=40~100%，T=6~60s。
