The maglev yaw system (MYS) of wind turbine adopts the maglev-driving technique instead traditional gear-driving technique, so it has advantages short downtime and low cost operation maintenance. However, is vulnerable to nonlinear time-varying disturbance caused by random change speed direction. This paper proposes a dual-loop suspension control strategy based on finite set model predictive (F...

MagneMotion and Old Dominion University undertook a cooperative agreement to demonstrate the MagneMotion M3 urban maglev technology on an existing elevated guideway on the ODU campus in Norfolk VA. M3 was designed for urban applications with speeds up to 100 mph, acceleration up to 1.6 m/s2, and a 60 foot turn radius. Figure 1 shows the “sled” vehicle on the ODU guideway. This vehicle was weigh...

The paper presents a generic modelling approach for electro-magnetic suspension (EMS) systems which brings together both fundamental principles and specific design factors to provide generalised models that can be adapted for any application. Key system parameters and typical electro-magnetic design factors are used to produce practical models for EMS controller design.

High-speed maglev train is considered an ideal vehicle in the 21st Century, as an important part of the train, the travel mechanism bears and delivers a variety of vertical and horizontal alternating load in operation, it affects the operation safety of the train directly, so key components of the travel mechanism should under fatigue strength test by fatigue test machine.The paper proposed a v...

1. Introduction From the principal point of view, the magnetic levitation is a method which is used for suspending an object in the air, without any physical contact. There are few main types of the magnetic levitation – electromagnetic, electrodynamic, transformation, superconductive and diamagnetic. All these are usually based on the force interaction between magnetic field and gravitation fi...
