| Abstract: | This dissertation explores the development of vector control for electric vehicles (EVs) and its integration into autonomous vehicle control and energy-saving strategies. The research focuses on the application of field-oriented control (FOC) techniques in steering maneuvers to optimize energy efficiency. The study investigates various speed change methods through experiments and analysis, aiming to provide insights into energy-saving approaches in EVs. The dissertation begins by addressing the urgency of addressing climate change and achieving carbon neutrality by 2050. It emphasizes the need for global efforts in the energy sector, particularly in renewable energy transition, energy efficiency, electrification of transportation, grid modernization, AI-controlled energy systems, and carbon capture and storage. Specifically, the research highlights the importance of energy-saving measures in the context of EVs due to their potential to revolutionize the transportation sector. It explores techniques such as regenerative braking, electric power steering (EPS), intelligent power distribution, and optimized motor control as means to enhance energy efficiency during steering maneuvers. FOC, a method used in motor control systems, is identified as a superior approach for speed control in EVs. The advantages of FOC include higher efficiency, enhanced torque control, better dynamic response, precise speed control, reduced torque ripple, improved low-speed performance, and a wide operating range. The study underscores the relevance of FOC in optimizing EV performance, increasing overall range, reducing environmental impact, and improving sustainability in transportation. The dissertation concludes by highlighting the favorable attributes of induction motors with FOC in EV applications. These include cost-effectiveness, robustness, availability and familiarity, support for regenerative braking, high efficiency, and power density. The research establishes the viability and potential of FOC techniques for energy-saving initiatives in EVs. Overall, this dissertation contributes to the advancement of vector control development for electric vehicles and its integration into autonomous vehicle control and energy-saving strategies. This study combines the technology of FOC control with energy-saving techniques during steering maneuvers in autonomous EVs to do some research and discuss different ways on speed change to save energy through experiments and analysis. The findings and insights presented offer valuable guidance for researchers, engineers, and policymakers in the pursuit of more sustainable and efficient transportation systems. |
