In order to enhance the fuel economy of hybrid vehicle and increase the mileage of continuation of journey, the power control strategy (PCS) is as significant as component sizing in achieving optimal fuel economy of the fuel cell/battery hybrid vehicle (FCBHV). The models of FCBHV structure and optimal power control strategy are developed by electric vehicle simulation software ADVISOR which uses a hybrid backward/forward approach. The results demonstrate that the proposed control strategy can satisfy the power requirement for two standard driving cycles and achieve the power distribution among various power sources. The comprehensive comparisons with the power tracking controller (PTC) which is wide adopted in ADVISOR verify that the proposed control strategy has better rationality and validity in terms of fuel economy and dynamic property in two standard driving cycles. Therefore, the proposed strategy will provide a novel approach for the advanced power control system of FCBHV. Keywords: FCBHV, Power Control Strategy, ADVISOR, Driving Cycles IntroductionHybrid vehicles are vehicles that use two or more power sources for the drive system. In contrast, ordinary internal combustion engine (ICE) vehicles use a single power source consisting of reciprocating engine, typically fueled with gasoline, to drive a complex transmission mechanism that is then coupled to the drive wheels [1], [2]. The disadvantages of ICE vehicles include low energy efficiency, excessive harmful chemical emissions, high noise level and heavy dependence on a single fuel source. Hybrid electric vehicles are one of the solutions proposed to tackle the perceived problems associated with the energy crisis and global warming [3]. Hybrid vehicles seamlessly combine two or more power sources into one drive system. The fuel cell/battery hybrid vehicle (FCBHV) merges hybrid vehicle and the hydrogen fuel cell technologies in order to replace the conventional fuel and optimize the fuel consumption.Power control strategy (PCS) and component sizing affect vehicle performance and fuel economy considerably in FCBHV because of the multiple power sources and differences in their characteristics. Furthermore, these two important factors are coupled-different selection of component sizing should come with different design of power control strategy. Therefore, to achieve maximum fuel economy for FCBHV, optimal power control and component sizing should be determined as a combined package. Our research has formulated and solved a power control problem of a FCBHV. Development of the power control strategy is one of the important tasks in developing hybrid vehicles and relatively many literatures can be found. Y. Guezennec et al. [4] solved the supervisory control problem of a FCBHV as a quasi-static optimization problem and found that hybridization can significantly improve the fuel economy of FCBHV. Wang Y et al. [5] used the equivalent consumption minimization strategy to determine an optimal power distribution for a fuel cell/supercapacitor hybrid ve...

“…Until now, most of the works focused on PEMFC control have addressed the improvement of PEMFC efficiency [25] and durability [26] separately. The present paper proposes a global solution to tackle the efficiency and durability improvement of the PEMFC power system at the same time, using state-of-the-art nonlinear control and observation techniques.…”

In this work, a nonlinear model predictive control (NMPC) strategy is proposed to improve the efficiency and enhance the durability of a proton exchange membrane fuel cell (PEMFC) power system. The PEMFC controller is based on a distributed parameters model that describes the nonlinear dynamics of the system, considering spatial variations along the gas channels. Parasitic power from different system auxiliaries is considered, including the main parasitic losses which are those of the compressor. A nonlinear observer is implemented, based on the discretised model of the PEMFC, to estimate the internal states. This information is included in the cost function of the controller to enhance the durability of the system by means of avoiding local starvation and inappropriate water vapour concentrations. Simulation results are presented to show the performance of the proposed controller over a given case study in an automotive application (New European Driving Cycle). With the aim of representing the most relevant phenomena that affects the PEMFC voltage, the simulation model includes a two-phase water model and the effects of liquid water on the catalyst active area. The control model is a simplified version that does not consider two-phase water dynamics.

“…The fuel cells are generally viewed as a dependable power source for many applications, such as hybrid vehicle, distributed power generation, and portable power source [15][16][17][18][19][20][21]. Due to slow dynamic characteristic of fuel cell, a fuel cell/battery (FC + B) or fuel cell/ultra-capacitor (FC + UC) hybrid vehicle has been proposed [5,22].…”
