Implementation of Closed Loop Pressure Control Using Virtual Instrumentation

Abstract

In the real world, most of the industries are under an obligation of control action to gain a desired performance of the process. In this paper, controlling of pressure using National Instruments Data Acquisition Device (NI DAQ) interfaced with LabVIEW software that provides better performance than conventional DAQ. The plant comprises of process station as well as the final control element. Virtual instrumentation rules the modern industries through its valuable contribution, especially for control engineers by powerful toolkits namely control and simulation, fuzzy logic and system identification toolkit. This work utilizes control and simulation toolkit and expresses Virtual Instruments (VI) for closed-loop control implementation to pressure process.
