摘　　要：工业过程控制中的被控对象具有非线性、纯滞后、多变量的特性。基于此,在图形化编程语言LabVIEW下开发基于动态查询表的模糊控制器,将合成推理法计算得到的动态查询表应用到NI CFP-2120控制器中,该控制器可以在极端环境中运行嵌入式LabVIEW应用程序,对三级串联水箱液位系统进行实时控制。实验结果表明,该模糊控制器具有无超调、非震荡、稳态误差小等特点,可用于实现LabVIEW下的模糊控制。The fuzzy control dynamic look-up table is developed under the graphical programming language LabVIEW for the controlled target which has the non-liner characteristic, the pure lag and the multivariable in the industrial process controlling. Depoly the dynamic look-up table calculated by compositional rule of inference to the NI Compact Filed Point（CFP）-2120 controller which runs the embedded LabV1EW application programs under the extreme environment, and the three-level series tank level system is real-time controlled. Experimental results show that the fuzzy controller has the excellent performance without overshoot, non oscillation and small static error, and a new method is provided to realize the fuzzy control under the LabVIEW program.
