Four In-Wheel BLDC Motors Speed Control in EV Based on Hybrid Fuzzy-PI Controller Visual on GUI

Recently, the increasing of usage transportation is impacted by air pollution caused by conventional vehicles which are driven by an internal combustion engine (ICE). The novel vehicle's research is to replace that engine with an electric motor, it is called Electric Vehicle (EV). This paper demonstrated a strategy of independent speed steering control for four in-wheels direct drive using brushless DC (BLDC) motors when the EV drives on a straight or curved road. A geometry model of the vehicle named Ackermann-Jeantand steering model is introduced to extract each wheel rotating speeds to avoid the wheel slide with the road during the EV operates on a corner street. The hybrid fuzzy-PI controller is used as a speed controller for each motor in the model in this design. The results are also compared with PI and fuzzy logic controllers. The results of two different modes have been illustrated on GUI with a satisfied response; thus, the control system has functioned correctly. It is revealed that the EV is driven and steered safely on the road.
