Backstepping control and energy management of hybrid DC source based electric vehicle

摘要

This paper presents a power management and backstepping control of electric vehicle DC power source. The hybrid DC power source consists of two energy sources: a fuel cell (FC) as a main source and battery as an auxiliary source; these sources are linked to the DC-bus through tow DC-DC power converters. The main focuses of this study is to ensure the power requirement of the traction machine using an appropriate power management strategy, to guarantee a good DC-bus regulation, and satisfactory tracking of the fuel cell and battery currents to their references. Simulations results are presented to verify the effectiveness of the proposed control strategy. These simulations are performed using the new European drive cycle (NEDC).
