This project mainly focused on designing a next generation controller for Pressure Process Station. The plant model was obtained using system identification toolbox. Using Ziegler Nichols tuning technique the controlling parameter for conventional control algorithm was initially implemented in MATLAB. In order to overcome the drawbacks of conventional controller, Fractional Order Proportional Integral Derivative controller (FOPID) which was implemented using Fractional- Order Modeling and control (FOMCON) toolbox in MATLAB. The hardware implementation was done by interfacing MATLAB with Arduino Mega 2560 as a low cost Data acquisition unit. The performance of the Fractional-Order Proportional Integral Derivative controller parameter was compared with that of the conventional controller.
