In this thesis we will study the importance of P, PI, PID controllers and we will examine some tuning methods. More specifically, we will study and compare the effectiveness of three popular methods of tuning parameters of a PID (Proportional-Integral-Derivative) controller: Ziegler- Nichols, Cohen-Coon, and Tyreus-Luyben. The study aims to evaluate the performance and stability of the control system using each tuning method and determine the appropriate method for different control systems. The results of the study show that each coordination method has its own strengths and weaknesses. To conduct the simulations, an N-order model is used and simulations are performed using each tuning method.In the first chapter we will analyze the historical background and conceptual framework of a PID controller. We will explain the physical meaning of the three controller terms and why parameter tuning is important. Then, in the following chapters we will examine tuning methodologies and how they are theoretically implemented and then develop codes for these methodologies in the Matlab programming environment. Through the thorough bibliographic study and the examples using Matlab we identify the differences and the usefulness of the methods.
