摘　　要：自动控制系统投入效果的好坏除工况外基本取决于控制方案、PID参数整定、测量元件和执行元件等4个因素。在实际运行中控制方案优劣、测量元件和执行元件好坏容易被人重视和发现,但PID参数整定工作往往容易被人忽略,一方面是基于仪表或工艺人员不具备整定能力,另一方面是PID整定工作需要花费精力多且周期长,综合两方面因素是导致化工装置整体自控率不高的主要原因。本文以电石炉炉压控制为例,介绍PID参数优化整定在投自动问题上的作用。The performance of the automatic control system depends on the control scheme, PID parameter setting, measuring element and actuating element, etc. In the actual operation control scheme and executive components, measuring element, and good or bad vulnerable to attention and found that the PID parameter setting work tend to be ignored, on the one hand, is based on the instrument or process people don＇t have the ability to set and on the other hand is PID setting work need to spend more energy and cycle is long, integrated the two factors are chemical device is the main reason for the overall control rate is not high. In this paper, the effect of PID parameter optimization on the automatic problem is introduced.
