Active In-Wheel Suspension System Design for On-Road Vehicles presents a comprehensive and systematic design and control framework for an Active In-Wheel Suspension System (IWASS), a transformative technology for modern on-road vehicles. This book addresses the fundamental challenge of integrating a high-performance active suspension actuator directly within the confined space of a vehicle's wheel. Taking a multidisciplinary approach which rigorously tackles the mechanical, electromagnetic, and thermal domains to create a viable and robust system, the work presents a complete trajectory from theoretical modeling and advanced control synthesis to high-fidelity simulation and rigorous robustness analysis. It therefore establishes a foundational roadmap for developing this disruptive automotive innovation. International case studies are integrated throughout, with summaries and problem sets at the end of each chapter to reinforce professional understanding of key engineering decisions. By consolidating key findings and charting essential future research directions, this book contributes significantly to the technologies that will underpin the next generation of vehicles, particularly as the industry evolves toward full electrification and intelligent, connected transportation systems. Designed to serve as a vital resource for automotive engineers, control systems researchers, and graduate students, it bridges the gap between theoretical control science and practical automotive engineering, offering both the depth required for specialists and the foundational context for those new to the field
