Designing a Fuzzy Slip Controller for DC Electrical Trains

This paper introduce a new slip control strategy based on the fuzzy controller to prevent train wheels from spinning out on low friction coefficient rails, especially during the acceleration process. In this paper, in addition to considering the dynamic model of the system, the dynamic equations of the traction motor is considered. Since the DC series motor has high starting torque, it is preferred to use this kind of motors in acceleration process.When slip occurs and increases, the voltage applied to the motorshould be reduced in order to decline motor torque employed tothe wheels, hence a fuzzy controller is introduced to generate theproper voltage for preventing the wheel spinning during theacceleration process. Finally, the simulation results are presentedto verify efficiency of the proposed controller.
