Fuzzy logic controller-proportional-integral for motor velocity control of electric rail train using DC-DC Converter

DC motor utilization is obtained in various of industrial activities and non- industrial activities. The utilization of DC motors in various purposes, it is necessary to control a velocity of the DC motor in accordance with a required velocity and this control can be conducted through a power converter. In this study, the utilization of DC chopper for velocity control of DC motor through Fuzzy logic controller proportional integral (FLC-PI) method for electric rail train is developed. The FLC-PI supports to achieve an adaptive controller. It has been adapted to achieve a good performance for auto tuning PI controller. The development process is conducted through simulation work with Matlab software. This study compares the performance between the system with PI control and FLC-PI control. The results of this study obtained the comparison between the PI and FLC-PI performances for the system without load are 1.06% and 0% overshoots respectively. In other to the comparison between the PI and FLC-PI performances for the system with load of 100 Nm are 0.5% and 0% overshoots respectively. And when the comparison between the PI and FLC-PI performances for the system with load of 200 Nm are 0.27% and 0% overshoots respectively. Thus, FLC-PI has shown more better performance than PI control.
