Decentralized control strategy of a fuel cell/secondary storage element power supply system |
|
Imad Eddine Aiteur, Cristina Vlad, Emmanuel Godoy(CentraleSupelec, France) |
| This article presents a decentralized control strategy
applied to a multi-source power system having a fuel cell (FC)
system as a main power source and a secondary storage element
(SSE) for peak current supply during transients and energy
recovery during braking. The dedicated control structure aims
to assure an optimal operation of the FC system and a desired
energy level of the SSE. To attain these objectives, a dynamic
model of the FC system (stack and auxiliary devices necessary
to fuel cell operation) is used, in addition to the SSE dynamics.

Bio Fuel Injection and Generated Voltage Change of Series Hybrid Electric Vehicle with Plant Oil Electric Generator |
|
Ayumi Sudo, Yoshihiko Takahashi(Kanagawa Institute of Technology, Japan) |
| We are developing a range extended electric vehicle using a diesel engine electric generator with plant (vegetable) oil (named as bio EV). The vehicle design concept is a series hybrid electric vehicle. A diesel engine rotates a DC motor by using plant oil to generate electricity, and the developed vehicle runs by using the generated electricity. It is possible to run a long distance without refueling, and plant oil fuels are sustainable natural resources. Generally, a fuel mixture consisting of light oil and plant oil is used as bio fuel. However, in this study, we only used plant oil (SVO: s |

Takeharu Hayashi(National Institute of Technology, Tokyo College, Japan), Yoshihiko Takahashi(Kanagawa Institute of Technology, Japan) |
| We have fabricated small sitting position-type electric vehicles in previous projects. In this study, we developed a small compact standing position ride-type electric vehicle for easy shopping. The vehicle’s operation system is designed to facilitate easy use by the elderly. The vehicle runs a longer distance, is easier to use, and reduces physical burden compared to our previously developed vehicle. Moreover, it saves energy as the acceleration time lengthens. |

Data Gathering System for Rescue Operations using ZigBee and Bluetooth |
|
PengYu Hsiao, Shigeyuki Tateno(Waseda University, Japan) |
| When disaster befalls, the most critical thing in rescue operation is construction the communication network to gather information from every rescue member. In this system, ZigBee is suitable as a node in a communication mesh network to assist the rescue operations in disaster areas. In this paper, the multi-hop experiment shows using ZigBee as routers are available to extend Bluetooth communication range. Furthermore, in a field experiment, the monitoring center is able to get the data from targets with low packet loss. |

Motion Detecting Method for Rescue Operation using Neural Network |
|
Shigeyuki Tateno, Yusuke Katafuchi(Waseda University, Japan) |
| In order to enhance performance and safety of rescue operations, a remote monitoring system with ZigBee wireless network has been developed. Using this system, the rescue headquarter on the base station of the network can gather the information about actions and positons of each rescue member. In this research, accelerometer and gyroscope data of IMU is used to measure members' motions, and behavioral characteristics of the motions is extracted from the data by using Neural Network in real time. |
