摘　　要：依托硝酸盐熔盐实验装置,基于半实物仿真方法,优化熔盐回路原有的比例、积分、微分(PID)控制,研究模糊控制方法在熔盐回路系统的适用性。结果表明:经过控制逻辑的优化,改进的PID控制器调节时间更短,超调更小,达到目标值后运行更加稳定;模糊控制方法也能满足预定的控制指标和性能要求,可作为大惯性熔盐系统温度控制的一种方法。Based on the nitrate salt experimental facility, the original PID controller of the facility is optimized and a fuzzy controller is studied to improve the temperature control performance of the experimental loop. The improved PID controller has shorter adjustment time and smaller overshoot. Besides, compared with PID control, the fuzzy control method can not only meet the desired control targets and demands, but also can be used to control the temperature in large inertia molten salt systems.
