Study and Design of a Magnetic Levitator System

Abstract

Magnetic levitation is one of the mechanisms that is at the forefront of technology. It is used in its most basic form in educational teaching, where the principles of physics converge that have as their principle electromagnetism and the fields created by existing poles that repel according to a quantity of initial current, giving instructive ideas of how the theoretical formulas work, giving life to a practical visual system. The current use on a large scale are the Maglev trains of Japan or superconductivity, being the realization of the quantum effects visualized at the moment of cooling the sample. The electronic circuit tends to be stable because, when using a high-power current, a Triac is needed to compensate the electrical flow provided by the operational amplifier and, therefore, stabilize with the photodiode when activated with the Led diode. Our purpose is to create a circuit that identifies the values of the electronic components that allow reaching equilibrium, with input and output variables that indicate the position and height of the object to be levitated.

Implementation of a Levitation System for the Visualization of the Magnetic Phenomenon

“…In equation (2), it can see that the terms mg f of the inductance are added to the force depending on the object, that is, x , that is, making a first expansion in L is:…”

“…Thus, with equations (5) and (6), it will have a system of two equations that allow to understand the laws of motion of the object to be levitated. Which according to [2] it will be possible to construct equations of state in the state space according to the degrees of freedom of the system.…”

“…The electronic components used for the design of the Levitation System are shown in the Table 2. The electronic components were following the research work [2], in addition to the use of its equation but adding an LDR that is will serve as a sensor for the activation and deactivation of the levitation system. Figure 3, the design of the previous research work was followed because this time with two different components that will be the sensors of our magnetic levitator circuit, in addition to indicating that it was verified that the consumption current of the electronic circuit was of 1 Ampere, this depended on the coil that was used.…”

“…It can be ensured that the theory is incomplete when it does not have the experimental part to observe these phenomena, being important to have both scientific experimentations equally. The fact of designing and implementing a levitator is of such importance, to generate interest in students who like science or not, can observe physical phenomenon [2], being through electronics the possibility of synthesizing the device with the electronic devices basics, without the need to use modern electronic devices such as Arduino or similar.…”

Development of a new linearizing controller using Lyapunov stability theory and model reference control

“…This method provided a limited degree of robustness because the total mass of the suspension could not be accurately measured. Claudio et al [22], the study and design of a magnetic levitator system based on electronic components were proposed. The electronic circuit developed provided a certain degree of stability when a triode or triode alternating current (TRIAC) was used to regulate the flow of current in the circuit.…”
