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。 Controlled industrial process control object has a nonlinear, pure lag, multivariate characteristics. Based on this, a dynamic look-up table-based fuzzy controller is developed under the graphical programming language LabVIEW. The dynamic look-up table calculated by the synthetic inference method is applied to the NI CFP-2120 controller, which can run embedded in extreme environments LabVIEW application that provides real-time control of three tandem tank level systems. Experimental results show that the fuzzy controller has no overshoot, non-oscillation, small steady-state error and can be used to realize the fuzzy control under LabVIEW.
