Adaptive Control of Fuel Cell and Supercapacitor Based Hybrid Electric Vehicles

Abstract

In this paper, an adaptive nonlinear control strategy for the energy management of a polymer electrolyte membrane fuel cell and supercapacitor-based hybrid electric vehicle is proposed. The purpose of this work was to satisfy: (i) tight DC bus voltage regulation, (ii) good fuel cell reference current tracking, (iii) better supercapacitor reference current tracking (iv) global asymptotic stability of the closed-loop control system, and (v) better vehicle performance by catering to slowly-varying parameters. We have selected the power stage schematic of a hybrid electric vehicle and utilized adaptive backstepping and adaptive Lyapunov redesign-based nonlinear control methods to formally derive adaptive parametric update laws for all slowly-varying parameters. The performance of the proposed system has been tested under varying load conditions using experimental data from the “Extra Urban Driving Cycle.” Mathematical analysis and Matlab/Simulink results show that proposed controllers are globally asymptotically stable and satisfy all the design requirements. The physical effectiveness of proposed system has been verified by comparing simulation results with the real-time controller hardware in the loop experimental results. Results show that proposed system shows satisfactory performance and caters for the time-varying parametric variations and the load requirements.

Renewable Energy Based Smart Grid Construction Using Hybrid Design in Control System with Enhancing of Energy Efficiency of Electronic Converters for Power Electronic in Electric Vehicles

“…In the literature, numerous control methods for energy management as well as control of HEVs are proposed [17]. A GA-based fuzzy logic controller has been developed to increase the performance as well as fuel economy of fuel cell-based HEVs [18]. To manage power as well as maintain level of charge in battery, an adaptive fuzzy logic based controller for fuel energy management as well as battery-based HEVs was utilised [19].…”

Hybrid Energy Storage System with Vehicle Body Integrated Super-Capacitor and Li-Ion Battery: Model, Design and Implementation, for Distributed Energy Storage

“…The classical application method of a switched-capacitor for vehicles is to add the super-capacitor to the battery. The technology uses simple series connection [21], and a planar and sandwich structure [22] has been reported, but the power level is still low and not suitable for electric vehicle applications. Our novel design is based on a new packaging concept that makes use of the vehicle body parts and, therefore, the power level and energy storage level are large and both series and parallel connections can be used.…”

Real-Time Control Strategy of Fuel Cell and Battery System for Electric Hybrid Boat Application

“…Some other researchers have been invested in the hardware in the loop and experiments to test the control strategies applied to HEV. The supercapacitor (SC) bank has been used at a transient state of operation, in addition to the FC [11]. The Lyapunov nonlinear control method has been applied to the simulation system based on HEV to estimate the converter control parameters.…”
