In this paper, a permanent magnet levitation system is introduced, and the ADRC controller is designed to enhance its control performance. Firstly, the variable flux path mechanism and mechatronic system structure are introduced, and the mathematical model of the system is established. Then, the ADRC controller is designed, and the control system simulation is performed. Finally, the levitation experiments are executed using a prototype, and the time-domain responses are analyzed. The results show that the control performance of the system with ADRC is significantly enhanced compared with PID.

In steel plate production lines at steel mills, steel plates are conveyed by rollers, which causes problems such as deterioration of surface quality due to contact. By installing electromagnets on the side of steel plates on the conveying path, this research group was able to obtain high inductive performance in experiments. However, the shape of the steel plate has not yet been obtained analytically. Therefore, focusing on multi-body dynamics, we are studying the optimal placement position of electromagnets. In this study, the behavior of steel plates when the damping coefficient is varied is analyzed using multi-body dynamics. The results showed that the behavior was close to that of actual free vibration experiments.

Permanent magnet elastomer particle using in this study is spherical particles dispersing neodymium fine particles in an elastomer. Damper force of a separated dual-chamber single-rod type damper using permanent magnet elastomer particles was investigated by experiments and numerical simulations. The effects of applying magnetic field were examined. The dependency of damper force on the frequency and stroke were also investigated. Behavior of magnetic elastomer particles inside the damper was simulated by using the discrete particle method.

Magnetic levitation is expected to transport thin steel plate without contact, however magnetic levitation is difficult because thin steel plate bend due to their flexibility. In addition, elastic vibration occurs in the steel plate during magnetic levitation. In order to improve the levitation stability, it is necessary to suppress the vibration of the steel plate. For this purpose, it is necessary to grasp the vibration of the steel plate, but it is difficult to experimentally grasp the vibration of the whole steel plate. Therefore, the vibration of the steel plate during magnetic levitation is clarified by numerical analysis. In this report, the usefulness of the proposed analysis method is clarified by com-paring the experimental results and analytical results.
