AN ELECTRIC BRAKING SYSTEM CONTROLLER FOR BRUSHLESS DC MOTOR IN ELECTRIC VEHICLE APPLICATION

In the world today, cities are getting more crowded with private mobilities and growing number of passenger vehicles because of which pollution index of cities is continuously increasing. Cities pollution levels are reaching to alarming rate giving rise to global warming. This can be avoided with the use of Electric Vehicle as it is pollution free and noiseless solution giving a same performance as like conventional gasoline powered vehicles. Nowadays electric vehicles are gradually coming on the roads in which a safety is very important parameter. The safety of passengers and driver is dependent on a braking operation. In this paper, brushless dc motor is used for motoring electric vehicle. This motor has various advantages like, high torque to weight ratio, constant torque and wide speed range. The designed controller model takes care of safety by intelligently sensing the speed and driver's requirement about braking through the brake pedal. The results of the proposed method are obtained and verified in MATLAB/ Simulink.
