Based on the decoupled control method of levitation and thrust forces in a single-sided linear induction motor (SLIM), a compact combined-levitation-and- propulsion SLIM Maglev vehicle can be realized without any additional levitation magnet When the vehicle runs, the levitation and propulsion forces varies depending on the phase of primary current because of the short primary end effect Especially the fluctuation of the levitation force causes the vertical vibration of the vehicle. To realize a high performance levitation and propulsion control by only SLIM, these fluctuations must be restrained. In this paper, levitation and propulsion forces were analyzed by using space harmonic analysis method and combined-levitation-and- propulsion control taking the fluctuation of the levitation and propulsion forces into consideration was proposed. It was verified by simulation that a stable and high performance combined-levitation-and- propulsion control can be realized.
