Abstract

This paper proposes a model-free control of a hybrid fuel-cell supercapacitor electric vehicle, where the complete vehicle propulsion system and energy dispatch control are independent of the system parameters. An ultra-local model of the fuel-cell and super-capacitor is considered herein for the precise energy dispatch control, while the permanent magnet synchronous motor is used for the vehicle propulsion system. The fuel-cell is the main power source while supercapacitor is considered as a backup power source with regenerative operation. Contrary to hybrid electric vehicle controls, the proposed system does not depend on the system modeling parameters. Consequently, the vehicle control inaccuracies caused by the changes in the fuel-cell, supercapacitor or motor modeling parameters are eliminated. Using the presented technique, rapid tracking of fuel-cell and supercapacitor currents to their reference values, as well as tight DC bus voltage regulation, has been demonstrated successfully. Additionally, a model-free control loop for a supercapacitor-fed converter for regenerative energy is analyzed. Rigorous simulations are carried out under manifold operating conditions, while the system is tested against various practical conditions in real-time using the Opal-RT 5600 platform, which validates the effectiveness of the proposed approach for practical implementation purposes.
