To achieve intelligent control algorithm in Foundation Fieldbus process control system, a method which combines LabVIEW and MATLAB to design a real time intelligent control system is presented in this paper. The intelligent control algorithm programmed in MATLAB can be stimulated by LabVIEW SIT, the communication between LabVIEW and fieldbus instruments can(More)
An Autoregressive model (AR model) based on Empirical Mode Decomposition (EMD) was applied to identifying gas-liquid two-phase flow regime. At first, the dynamic differential pressure signals coming from Venturi tube were processed by normalization, EMD and denoise. Afterwards, the Intrinsic Mode Functions (IMF) contained flow regime information were(More)
In order to carry out the line identification of gas-liquid two-phase flow pattern, a gas-liquid two-phase flow pattern automatic identification system on virtual instrument technology was put forward. The fuzzy controller was designed by the Fuzzy Logic for G Toolkit of LabVIEW. Its input were two eigenvalues, which were self-defined and could describe the(More)
To improve the automation level of flow measurement device in the lab, enhance the ability of experiment, and make the efficiency of using these equipments higher, a remote measurement and control system for flow meter verification which based on Labview and PLC is designed in this paper. This system can realize volume and master meter method for(More)
