A Parallel Energy-Sharing Control Strategy for Fuel Cell Hybrid Vehicle
Abstract:
This paper presents a parallel energy-sharing control strategy for the
application of fuel cell hybrid vehicles (FCHVs). The hybrid source discussed
consists of a fuel cells (FCs) generator and energy storage units (ESUs) which
composed by the battery and ultracapacitor (UC) modules. A direct current (DC)
bus is used to interface between the energy sources and the electric vehicles
(EV) propulsion system (loads). Energy sources are connected to the DC bus
using of power electronics converters. A total of six control loops are
designed in the supervisory system in order to regulate the DC bus voltage,
control of current flow and to monitor the state of charge (SOC) of each energy
storage device at the same time. Proportional plus integral (PI) controllers
are employed to regulate the output from each control loop referring to their
reference signals. The proposed energy control system is simulated in
MATLAB/Simulink environment. Results indicated that the proposed parallel
energy-sharing control system is capable to provide a practical hybrid vehicle
in respond to the vehicle traction response and avoids the FC and battery from
overstressed at the same time.
