基于遗传算法的蒸发器水位PID控制研究

PID Control for Nuclear Steam Generator Water Level Based on Genetic Algorithm

摘要: 由于缩胀效应的存在，反应堆蒸汽发生器是一个非最小相位系统。在分析蒸汽发生器运行机理的基础上，根据压水堆蒸汽发生器的简化数学模型，设计了1种整定PID控制器的遗传算法。利用Simulink仿真的结果表明，水位控制效果良好。

Abstract: The nuclear steam generator is a nonminimum-phase system, which is caused by the swell and shrink effects. Based on the analysis of the mechanism of steam generator, the PID controller with a simplified steam generator model was tuned offline by the genetic algorithm in the paper. The simulation results from Simulink demonstrate that the developed level controller is in good performance.
