Semi-Active Magnetic Levitation System for Education

Applied Sciences

This paper describes how to construct a low-cost magnetic levitation system (MagLev). The MagLev has been intensively used in engineering education, allowing instructors and students to learn through hands-on experiences of essential concepts, such as electronics, electromagnetism, and control systems. Built from scratch, the MagLev depends only on simple, low-cost components readily available on the market. In addition to showing how to construct the MagLev, this paper presents a semi-active control strategy that seems novel when applied to the MagLev. Experiments performed in the laboratory provide comparisons of the proposed control scheme with the classical PID control. The corresponding real-time experiments illustrate both the effectiveness of the approach and the potential of the MagLev for education.

Modeling and Control Design of an Educational Magnetic Levitation System

Linköping electronic conference proceedings, 2023

A magnetic levitation system is a perfect educational example of a nonlinear unstable system. Only with suitable control, a small permanent magnet can be held floating stable below a coil. After modeling and simulation of the system, control of the system can be developed. At the end, the control algorithm can be coded on a microcontroller, connected to a pilot plant.

Magnetic Levitation Training Kit for Teaching Basic Electrical Control System Courses

In this paper, we propose a training kit for developing a system to assist basic electrical control courses to the undergraduate students of Electrical Engineering or Electrical Engineering Technology. We present magnetic levitation hardware demonstrating a load hanging in the air with the help of electromagnetic coil. The students are provided with unassembled training kit project where they will use it to achieve several learning outcome. Technical data of the system is given along with a basic instruction manual as benchmark for the training kit. The magnetic levitation kits provide an open-ended design problem such as designing a sensor, load, closed loop feedback system and a lot more. The training kit is alter made to provide exciting and excellent teaching tools for controls system subject unlike the conventional trainer module.

COBEM-2017-0161 MODELING AND CONSTRUCTION OF A MAGNETIC LEVITATOR APPLIED IN AN ACADEMIC ENVIRONMENT

Magnetic levitation is a phenomenon by which a ferromagnetic body floats due to the action of a magnetic field, which generates a force that enters in balance with the gravitational force. In this work, it is proposed the modeling and construction of a magnetic levitation system, and also it's considered the levitation position tracking problem of a set of neodymium magnets. The design and construction of the levitation system are performed using free software. The model obtained it's the type of non-linear and third order. In this work, it's proposed a PID controller (Proportional, Integral and Derivative) to tracer the magnets. For the controller design it's used the linearized model of this system. Numerical simulations show the effective position tracking of the control system designed for this application. The modeled systems are executed in analogical and digitals electronics circuit, previously simulated and optimized, which will control the neodymium magnets levitation on a balanced position that will be provided by the student.

Development of magnetic levitation system with position and orientation control

International Journal of Reconfigurable and Embedded Systems (IJRES), 2023

This work demonstrates the design and development of a magnetic levitation (MagLev) system that is able to control both the position and orientation of the levitated object. For the position control, a pole placement method was exploited to estimate parameters of the proportional integral derivative (PID) controller. In addition, the MagLev was constructed using a pair of electromagnets, two infrared (IR) receiver-emitter pairs and a servo motor to allow the orientation of the object to be controlled. The proposed controller was programmed in a Lab-VIEW environment, which was then compiled and deployed into an embedded NI myRIO board. Experimental results demonstrated that the proposed method was able to achieve a zero steady-state orientation error when the object was rotated from 0 • to ±90 • , a steady-state position error of 0.3 cm without rotation, and steady-state position errors of no greater than 1.2 cm with rotation.
