摘要: 针对直流蒸汽发生器(OTSG)二次侧水容积小、蓄热能力低,且在功率变化过程中,其给水流量和反应堆的功率应迅速匹配以保证OTSG二次侧蒸汽品质的问题,将T-S型神经模糊控制原理引入到OTSG的给水控制系统中,设计一种基于数值仿真输入输出数据的T-S型神经模糊控制器,并对其控制结果进行仿真验证。结果表明,该控制方式可以取得更好的控制效果,且满足各工况下的控制需求。

Abstract: Considering the problems of small water inventory and inferior heat accumulation capacity of the secondary side of the once through steam generator（OTSG）,and the need of rapid match of feedwater flowrate and the reactor power to ensure the steam quality,the T-S fuzzy neural method is incorporated into the OTSG feedwater control system to design a T-S fuzzy neural controller based on input and output data acquired by numerical simulation.The control results are verified by simulation method.The simulation results show that the control results under this control manner are better than those under the PID control manner and meet the control requirements satisfactorily.
