Design of a fuzzy-based pressure control using SCADA

چکیده مقاله

SCADA (supervisory control and data acquisition) is a technology that let users to collect information from distant installation and send the control instructions. In this kind of system, user give all the observed instruments information like gas and oil installation, pipe lines or power stations, opening and closing valves and switches, showing alarm and collecting measured information in a distributed control system(DCS) room according to these situations implemented the control instructions. Pressure physical quantity is one of the useful quantities in industrial processes especially in oil, gas and petrochemical industries. In this work, designing the pressure quantity controller has been proposed base on the fuzzy logic and using SCADA information. The point of this purpose has been proposed using the graphic user interface (GUI), a model for monitoring tank output pressure variations with the setpoint signal conditions that makes user enable to study the results of control purpose exertion on the system besides setpoint signal conditions variation. Simulation results on tank pressure demonstrate the proper accuracy and controller speed in tracking setpoint signal.
