DESIGN OF AN ELECTRONIC CONTROL SYSTEM ON PRESSURE IN OIL INDUSTRIES USING ELECTRONIC PROPORTIONAL CONTROLLER.

Abstract

There is an important need in the industrial applications to have a control system by which we can control the flow rate ,pressure ,and differential pressure of a fluid especially in the Industrial applications. There are some methods used to control the above quantities. For example the computer control method ,the programmable logic controller method . These methods have advantages and disadvantages ,where their advantages are having high speed control and accuracy , while their disadvantages are having high cost and sometimes are not available. This paper presents a new and a low cost way to control on the (flow rate ,pressure ,and differential pressure ) in oil industries. In this paper a proportional controller had been designed ,where this controller consisted of two parts the first is responsible for the required set point ,and the second for comparing the received signals coming from the transducers with required set point signals.
