Design and Control of Multifunctional Electromagnetic Dampers for Enhanced Vehicle Suspension Performance

<p dir="ltr">The suspension system plays a crucial role in ensuring vehicle ride comfort, handling stability, safety, and energy efficiency, especially with the growing demands of modern passengers and drivers. This thesis develops multifunctional electromagnetic dampers (MFEMDs), an emerging suspension technology. These dampers integrate the advantages of multiple suspension types through electrical network design and control strategies. This research proposes multifunctional electromagnetic damper (MFEMD) systems and their control strategies. The goal is to achieve a balanced improvement in ride comfort, handling stability, and energy efficiency.</p><p dir="ltr">The traditional four types of suspension systems—passive, active, semi-active, and energy regeneration suspensions—each have distinct advantages and limitations in terms of ride comfort, handling stability, road-holding performance, and energy efficiency. By combining the strengths of these systems, MFEMD systems can overcome individual disadvantages, achieving both improved energy efficiency and enhanced vibration control performance. This promising capability has driven the rapid development of multifunctional suspensions such as MFEMDs.</p>
