非线性PID调节器及其在DCS中的应用

The Application of Nonlinear PID Modulator in DCS

介绍了非线性ＰＩＤ调节器的一般理论，给出了非线性ＰＩＤ调节器控制在分布式控制系统ＤＣＳ中的实现方法，经过实际的现场应用表明，非线性ＰＩＤ调节器明显优于常规ＰＩＤ调节器，取得了比较好的应用效果。

At first,this paper introduces the general theory of nonlinear PID modulator. Then it pre-sents the method how nonlinear PID modulator is applicated in the Distributed Control System(DCS). Practical site-application shows that the nonlinear PID modulator is obviously betterthan the general PID modulator. We received better application result.
