Mathematical modeling and control of active suspension system for a quarter car railway vehicle

Active suspension is a term where active components are incorporated in a mechanical suspension system. Compared to passive suspension, the active suspension provides improved feature of suspension in terms of ride quality and vehicle handling. While the passive suspension consists of spring and...
