10MW高温气冷堆 (HTR 10 )动力系统自动控制的研究中 ,给水流量调节回路是其底层的三个重要回路之一。由于对象存在着非线性特性及参数变化范围大等特点 ,给控制器参数的工程整定带来很大困难。本文针对研究的需要建立了适用的回路模型 ,通过仿真总结了该回路PID控制器的参数调整方法和规律 ,对控制系统的工程实现和现场整定有直接的参考作用及指导意义。 In the study of the automatic control of a 10 MW high temperature gas cooled reactor (HTR 10) power system, the feedwater flow control loop is one of the three important loops at the bottom. Due to the non-linearity of the object and the wide range of parameters, it is very difficult to set the parameters of the controller. In this paper, a suitable loop model is established according to the needs of the research. The method and rule of adjusting the parameters of the loop PID controller are summarized through simulation, which has direct reference and guidance to the project implementation and site setting of the control system.
