Implementation of Fuzzy Logic Control for Soft-Starting Method Brushless DC Motor at Electric Bicycle

Electric bike is one of electric vehicle started to developed in much way. Electrical energy converted into mechanical energy used to energy supplies for electric bike, this way energy converting method are more environtmental friendly in a while CO2 is one of the biggest pollutant that caused global warming. Electric bikes use battery power as a source of energy. Electric bicycles consist of two main parts, namely bicycles and electrical components. The electric component consists of a 48 volt battery, controller, three phase inverter, microcontroller and a 350 watt BLDC motor that is coupled and connected into a bicycle. Fuzzy logic control used to regulate the soft-starting process on an electric bicycle. The BLDC starting motorbike on an electric bicycle requires currents that reach up to 6 A if not controlled. So it needs to be controlled. After being given fuzzy logic control where the settings are placed at the set speed point, the starting motor current on the electric bicycle without the driver has a value of 0,9 A with a steady state condition of 0,2 A, and when riding the driver weighing 50 Kg, the starting current reaches a value of 3,9 A. the difference in the starting current that is more red when using fuzzy logic control proves that the use of fuzzy logic control programs can make electric bikes soft-start and save energy.
