用齐格勒-尼柯尔斯法则调整的PID控制器改造离心铸管机的液压控制系统

PID Controller Modulated with Ziegler-Nichols Theorem Reconstructs the Control System of Centrifugal Pipes Casting Machine

离心机的主机行走是控制铸管质量的主要环节 ,采用闭环控制系统是解决这一问题的关键。本文对DN4 0 0～ 80 0离心机的自身开环控制系统 ,提出对控制系统的闭环改造 ,以齐格勒 -尼柯尔斯法则对PID控制系统进行分析与研究。

The move of centrifugal machine is the main tache to affect the quality of pipes. The key to resolve this problem is to apply closed loop system. This paper gives a method for the opened loop system of DN400～800 centrifugal machine to reconstruct with a closed loop system, and analyzes and studies the system with Ziegler Nichols theorem.
