Abstract: All the industrial process applications require robust position control of DC motor. The aim of this paper is to design a robust position control of DC motor by selecting different controllers like P, PI, PID and their tuning methods. The model of a DC motor is considered as a third order system with incorporating uncertainty. This paper compares the different kinds of tuning methods of parameter for PID controller. One is the controller design by Zeigler and Nichols method, second is the auto tuning of the controller in basic design mode and third is in the extended design mode. It was found that the proposed PID parameters adjustment in the basic and extended design mode is far better than the P, PI and Zeigler and Nichols method. The proposed method could be applied to the higher order system also.
Keywords: Basic mode, DC motor, PID tuning, robust position control.
