Tuning methods for improving the performance of the controller

Abstract

The technology used in the process industries has changed rapidly newlinein recent years as plant processes have become more and more complex newlineThese changes are due to the increasing need for better product quality and newlinethe need for minimizing of operating costs As a result significant new newlineconstraints have emerged which reflect directly on plant process technology newlineThe capability and availability of new modern hardware and software also newlineplay an important role in this advancement of technology within the process newlineindustries With new technology in the field of Instrumentation and newlineMeasurement more accurate and precise data can be provided newlineIn this research work tuning of a PI controller for servo and newlineregulatory pH process as well as heat exchanger with bypass and sensor has newlinebeen carried out pH is one of the important parameter which has to be newlinecarefully controlled in most of the industries such as waste water treatment newlineelectro hydrolysis pharmaceuticals and other industries newline newline
