Comparative Study of Controller Scheme and Tuning Methods

Abstract

The adjustment of a control parameter to produce a sufficient response to the processing system is known as tuning a control loop. Control procedures are frequently tweaked during running conditions rather than startup conditions to ensure that the process variable is stable at an operating point. Proportional Integral Derivative (PID) are the extensively used controllers to compensate for a wide range of industrial processes due to their simplicity and resilience. The effectiveness of tuning procedures has been compared using time response characteristics. This study shows how to adjust the gains of the Proportional Integral (PI), Proportional Integral Derivative (PID) and Fractional Order Proportional Integral (FOPI) controllers by using various tuning methodologies. The method involves calculating the Controller Gain (Kc), Integral Time Constant (TI), and Derivative Time constant (TD) for a PID-controlled system with a First-Order Plus Time Delay (FOPTD) process. MATLAB / SIMULINK platform is used to investigate and evaluate the performance of various PID tuning procedures in this study. © 2022 IEEE.
