Proportional-Integral-Derivative Controller Adjustment Using Different Methods

Abstract

The Proportional, Integral and Derivative controllers are the most widely used controller in the industries. Simplicity, successful practical applications and near optimal performance are some of the reasons that have made PID control so popular in the academic and industry researches. Recently, it has been noticed that PID controllers are often poorly tuned (obtaining the controller parameters Kp, Ti, and Td) and some efforts have been made to systematically resolve this matter. Many tuning methods have been proposed for obtaining better PID controller parameter settings. The comparison of various tuning methods for First Order Plus Dead Time (FOPDT) process are analyzed using MATLAB simulation to determine the best method for the system.
