Electric vehicles (EV s) boast zero tailpipe emissions, directly improving air quality and lowering greenhouse gas emissions. Despite the promise of EVs for sustainable transportation, their limited range is a key challenge. Regenerative braking is a promising approach for enhancing the driving range. This research proposes a study of Interval Type-2 Fuzzy Logic (IT2FL) control to improve regenerative braking efficiency in an electric trike. Employing IT2FL control for regenerative braking recovers 35.84% of energy, translating to a 91.053 km increase in driving range. The IT2FL method achieved a range of 50 km/kWh, representing a significant 41.7% improvement. Furthermore, utilizing the Nie-Tan Method reducer within the IT2FL framework could extend the range by an additional 2.3 km, resulting in a 3 % increase in energy recovery. These findings demonstrate the effectiveness of IT2FL control in enhancing regenerative braking efficiency for the electric trike. © 2024 IEEE.

Optimizing regenerative braking systems in electric vehicles presents a complex challenge requiring precise and adaptable control. This research proposes employing K-Means Clustering to the Interval Type-2 Fuzzy Logic (IT2FL) membership functions, thereby improving overall regenerative braking efficiency and enhancing driving range. This research demonstrates that implementing a K-Means in the IT2FL control system in electric vehicles effectively recovers 35.84% of energy. By incorporating a K-means-based approach, the IT2FL controller further enhances vehicle range by 43 kilometers, achieving a total range of 108 kilometers. In comparison, an IT2FL system without K-means recovered only 26.67% of energy and achieved a total range of 93 kilometers. Notably, the IT2FL controller with K-means enabled the electric vehicle to attain an energy efficiency of 22 kilometers per kilowatt-hour. These findings underscore the significant improvement in maximum range offered by the IT2FL controller with K-means compared to alternative methods. © 2024 IEEE.

Investigation on the Power Consumption of an Electric Vehicle Powertrain Using Electro-mechanical Continuously Variable Transmission with Variable Metal Belt's Clamping Force

SSRN 2024年

This research presents an investigation to determine the potential of an electro-mechanical CVT (EMCVT) in reducing the power consumption of an EV powertrain. The investigation starts with the experimental phase, conducted to obtain the efficiency data of the EMCVT prototype. In the phase, the prototype is tested for the geometrical ratio (rCVT_geo) of 2.30, 1.60, 1.00 and 0.70, with the variable clamping force of 8.5 kN, 10.5 kN and 11.0 kN applied on its secondary pulley. The results show that with the lower clamping force, the transmission efficiency can be improved by up to 10%, depending on the ratio. With the EMCVT efficiency data, the simulation phase of the research is carried out, in which the power consumption of the EMCVT-based EV powertrain is compared to the single speed transmission. The results explain that for the combined low and medium phases of the Worldwide Harmonized Light Vehicles Test Cycle (WLTC), the EMCVT performs slightly worse;0.01 kWh more power consumed that the single speed transmission. However, for the entire WLTC, it fares better, recorded 3.47 kWh compared to 4.67 kWh of the single speed transmission, suggesting the potential of the prototype for implementation in an EV powertrain. © 2024, The Authors.

In this research, a high-altitude, compact and rapidly deployable, air-launched, inflatablewinged aircraft is designed, developed, and flight-tested to investigate the flight characteristics of inflatable-winged aircraft as well as the in-flight inflation and dynamic deployment properties when launched from various carriers. To start with, two types of inflatable wings employing different materials have been designed, fabricated, and tested, the tests including structural characteristics tests, inflation properties tests, and low-Reynolds-number wind-tunnel tests. A full-scale 30-kilogram prototype unmanned aerial vehicle with inflatable wings was then designed, assembled and tested with some basic low-altitude flights to verify the feasibility of the aerodynamic layout and the trim and stability and control characteristics. Finally, low- and high-altitude in-flight launches will be conducted to study the dynamic deployment properties and high-altitude flight characteristics of this design. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA.

作者： Pannathorn Jitpratak Akhilesh Kumar Pathak Kankan Swargiary Charusluk Viphavakit Department of Biomedical Engineering Faculty of Engineering Chulalongkorn University Bangkok Thailand Department of Mechanical Engineering Center for Smart Structures and Materials Northwestern University Evanston IL USA Faculty of Engineering International School of Engineering (ISE) Intelligent Control Automation of Process Systems Research Unit Chulalongkorn University Bangkok Thailand

An optical fiber sensor with a single mode-multimode-single mode (SMS) structure is proposed to detect ethanol vapor ranging between 100–500 ppm via the evanescent field interaction at the interface between the optical fiber and ethanol vapor. The proposed optical fiber sensor offers real-time and non-invasive monitoring of ethanol vapor, which is one of the biomarkers of diabetes. Molecular imprinted polymer (MIP) is coated at a multimode fiber region, which is considered to be a sensing area, to improve the selectivity of the ethanol biomarker. The sensor works based on wavelength interrogation by detecting the change in wavelength due to the change in vapor concentration. The fabricated sensor has a sensitivity of 0.0013 nm/ppm, which suggests the potential to be used as a monitoring device for breath analysis.
