Implementation of fuzzy logic controller for parallel hybrid electric vehicle

In this paper, implantation of fuzzy logic controller for parallel hybrid electric vehicles (PHEV) is presented. In PHEV the required torque is generated by a combination of internal-combustion engine (ICE) and an electric motor. The controller simulation using the SIMULINK / MATLAB package. The controller will be designed based on the desired speed for driving and the state of change of speed. In the other hand, performance of PHEV and ICE under different road cycle is given. The hardware setup is done for electric propulsion system; the system contains the induction motor, the three phase IGBT inverter with control circuit using microcontroller. The closed loop control system used a DC permanent generator whose output voltage is related to motor speed. Simulation and experimental results show very good performance.
