DC motors have a wide range of usage in the industry. So its control is one of the important topics. In literature, there are different control algorithms for the speed control of DC motor. This paper presents a comparative study of PI and Self-Tuning PI controller for the speed control of DC motor. DC motor is modeled and classicPI controller applies for the speed control of DC motor. Pole Placement method is used to get parameters of the PI controller which are Kp and KI. Fuzzy Logic is used for Self-tuning PI controller design. In this controller, Kp and KI controller gains are adjustable parameters and are updated depending on the speed error and change of error. Simulations of these two controllers are performed in the Matlab/Simulink. PI and Self-tuning PI controller are compared and results are given in graphs. The simulation results show that the Self-tuning PI controller has better efficiency than the classic PI controller.
