Abstract

Journal of Vibration and Control, Ahead of Print.
Maglev electromagnetic suspension (EMS) under dynamic operation is challenged by track-induced disturbances and modeling uncertainties, leading to levitation-gap oscillations and steady-state bias. A semi-bogie EMS model is developed, and Lyapunov-based ...
