How does a modular magnetic levitation system work?

A modular magnetic levitation system with static square coils and a moving 2D Halbach array is proposed in this paper. The mover achieves six degrees of freedom (DOF) motion with long stroke translational motion and yaw motion. A novel 2D lookup table is used to model the force and torque on the mover, including the edge effect.

What is a magnetic levitation system?

1. Introduction Magnetic levitation (Maglev) systems are of increasing interest in manufacturing and production lines, with the potential to replace traditional conveyor systems and aid in flexible manufacturing. Maglev systems utilize electromagnetic coils to levitate a magnetized object without mechanical connection.

What is magnetic levitation system (MLS)?

By magnetic levitation system (MLS) we mean any device that uses a controlled magnetic field to suspend an object and move it in a specific direction. Contactless, frictionless, and noiseless motion caused by MLS has been successfully applied to numerous fields of advanced technology, such as: vibration control 5.

Is magnetic levitation a good control technique?

Performed tests and experiments demonstrate that the proposed control technique is robust against discretization and unknown MLS model parameters, provides high tracking accuracy, is easily implementable, and simple to tune. Magnetic levitation is a modern technology that is a subject of intensive research.

Can fuzzy inversion be used to control magnetic levitation?

The approach based on the fuzzy inversion proposed here can be a good starting point to remove the assumption of strict-feedback form. This indicates a possible direction for future work. The proposed technique can be successfully used to control more complex systems using the magnetic levitation phenomenon.

Which controllers are used in Maglev levitation control?

Most of reported results concentrate on using artificial neural networks or fuzzy systems to modify (optimize) on-line the parameters of other controllers, such as PID and state feedback controllers in maglev levitation control. Careful inspection of references indicates that linear controllers are mostly used, especially in practical applications.
