Electrification in non-road and road scenarios

This thesis investigates the electrification of construction machinery, emphasizing its potential to enhance efficiency, reduce environmental impact, and increase operational versatility. While road vehicle electrification is well-established, construction equipment is only beginning its transition. The study explores the integration of electric solutions, addressing challenges such as the reliability of electronic controls and the development of innovative algorithms to manage noise and vibrations from electric drives. Collaborating with Casappa S.p.A., the research focuses on electrifying fan drives traditionally powered by hydraulic systems. An integrated motor and inverter design enables easy installation in new machines and retrofitting of existing machinery, enhancing operational flexibility while maintaining high power output in challenging conditions. The thesis further examines control strategies, comparing classic proportional integral PI controllers with adaptive two dedrees of freedom 2-DOF regulators to optimize performance and minimize torque disturbances. Additionally, the thesis addresses active noise reduction in electric motors. The thesis terminates in a test bench creation for experimental investigations of electromagnetic fields effects on bituminous materials due to a wireless vehicle charging system, to assess their long-term effects. This multidisciplinary approach aims to pave the way for a more sustainable and efficient future in construction machinery.
