摘　　要：为解决热力站供暖系统中的供水分系统和补水分系统采用传统PID控制算法对应的控制精度低、稳定性差等问题,在对热力站供暖系统基本组成和供水、补水系统分析的基础上,分别以供水系统和补水系统为研究对象,对其当前控制系统存在的问题进行分析,提出了以自适应模糊PID控制对供水系统进行优化控制,以前馈-串级控制器对补水系统进行优化控制。通过仿真计算验证了优化控制的效果。In order to solve the problems of low control accuracy and poor stability corresponding to the traditional PID control algorithm of the water supply subsystem and water replenishment subsystem in the heating system of the thermal station,based on the analysis of the basic composition of the heating system and the water supply and water replenishment systems of the thermal station,the water supply and water replenishment systems are respectively the objects of study,and the problems of the current control system are analyzed.PID control for water supply system and feed-forward-serial controller for make-up water system;finally,the effect of optimal control is verified by simulation calculation.
