Abstract

Hybrid Electric Vehicle (HEV) is vehicle with least two energy sources, such as Internal Combustion Engine (ICE) and Brushless DC Motor (BLDCM). BLDCM provide additional torque, to purpose of HEV can reach the set point speed according to the reference model. Commutation of BLDCM still complicated, because between the rotational speed of the motor and the speed of the rotary field on the stator should be kept synchronized. Self Commutation used to maintain synchronization between rotation of the rotor and rotary field velocity on BLDCM stator. In addition, this research also applies torque control strategy by using fuzzy-PI controller. Vehicle performance still follows the reference curve with steady state error of 0.1506 km/h and RMSE relative response speed HEV <2%

Abstract

The induction motor is a desirable alternative to the direct current motor in many applications because it is rugged, reliable and economical. However, control of the induction motor is more complex than the direct current motor, this is caused by the complexity of the dynamics of the induction motor, so the algorithm of induction motor is more complex. Based on these problem, author conducted a study on the induction motor using Model Predictive Torque Control (MPTC) with robust stator flux observer, in which robust stator flux observer is designed to overcome the shortcomings in the Direct Torque Control (DTC) conventional which can cause high fluctuation in flux ripple and torque ripple when reach steady state condition. So from the purpose of the proposed method, the results of the designed system can adjust the rotating speed of the induction motor in accordance references given at 120 rad/s with a settling time is 0.753 seconds, and also can minimize fluctuations in flux ripple and torque.
