Magnetic levitation and propulsion systems have been studied and the gap length control and propulsion control characteristics are clarified. The voltage equation for the single-sided linear induction motor (SLIM) is derived with consideration of the gap length dependence. Also, the transfer function of the control system is obtained by the state variable method to clarify the characteristics of the gap length control loop and the propulsion control loop. The experiment is made using a model system and the frequency and step responses are compared with the analysis results. The features and problems of the magnetic levitation and propulsion system are discussed in comparison with the attraction-type magnetic levitation system.
