Studying The Theory of PID Controller & Comparing Its Tuning Methods

Abstract

Proportional, Integral and derivative (PID) controllers a control strategy that has been successfully used over many years. Most widely-used controller in the industries because of their simplicity, robustness and successful practical application. PID controller have many type (P, PI, PD, PID) is this research will study the design and theory of it. Many tuning methods have been proposed for PID controllers. In this study will compare some of these tuning methods for step input with third order system with the aid of MATLAB and SIMULINK we extract the results and compare the result
