Active and Semi-Active Suspension Systems

This book comprehensively explores fundamental aspects of adaptive vehicle suspension systems, offering numerous examples for suspension modeling, control, estimation, and fault diagnosis and prognosis methodologies. It is intended for senior undergraduate and graduate students, vehicle R&D departments, and anyone with an interest in the design and control of adaptive or active suspension systems. In order to simplify the understanding of more difficult concepts, the book uses a step-by-step approach along with pictures, graphs, and practical examples. The book begins with an introduction of vehicle adaptive suspensions, highlighting some common mass-produced products in recent decades. Furthermore, three widely-used mathematical models of adaptive suspension systems are derived. Subsequently, four suspension control algorithms and gain-adaptive approaches are introduced, accompanied by MATLAB/Simulink programming examples for enhanced understanding and practical implementation. Lastly, the fault diagnosis and prognosis of adaptive suspension systems are introduced.
