在炼钢生产过程中,需要对工艺过程和生产设备进行控制,使被控制的物理量保持在一定的范围内,PID控制应运而生。本文通过介绍PID的原理及系统的设计与实现,向大家展示了分段PID在首钢京唐公司炼钢吹炼过程中的良好运用,保证了生产运行和产品质量的稳定。 In the process of steelmaking, the process and production equipment need to be controlled so as to keep the controlled physical quantity within a certain range, and the PID control comes into being. This article introduces the principle of PID and the system design and implementation, to show you the segmented PID in Shougang Jingtang company steelmaking process of good use, to ensure the production and operation of product quality and stability.
