Abstract

Hybrid Electric Vehicle (HEV) is vehicle with least two energy sources. Internal combustion engine (ICE) and BLDCM are combination of commonly used energy sources. BLDCM serves to provide additional torque, with the purpose of HEV can reach set point speed according to the reference model. Commutation of BLDCM is still quite complicated because between the rotational speed of the motor and the speed of the rotary field on the stator shall be kept synchronized. Self Commutation is used to maintain synchronization between the rotation of the rotor to rotary field velocity on BLDCM stator. In addition, this research also applies torque control strategy using fuzzy-PI controller. The BLDCM Self commutation scheme can be applied to the HEV plant. The applied strategy can reduce undershot at HEV speed by represents steady state error value of 0.0049 rpm.
