Design, analysis, set‐up fabrication, control, and a novel analytical approach of a levitation prototype for a symmetric shaped object

Abstract

This paper highlights the design, electromagnetic analysis, system modelling, set-up fabrication, and finally control of an attraction type lab developed levitation prototype. The objectives of this work are parameters' evaluation, for example, force, inductance, and current-air-gap characteristics using a novel analytical model, electromagnetic results, and practical experiments.The FE model has been built using standard packages. A novel permeance function-based approach is developed for the analytical evaluation of parameters. These are verified by actual experiments too with excellent correlation between the sets of results. Agreement between analytical and practical values also show that the modelling is perfect and reliable which further leads to accurate design, fabrication, and implementation of the controller. A simple but reliable controller has been designed, analyzed, and implemented. The performances have been significantly improved. Finally, the steel object has been successfully and steadily levitated in robust condition.

“…The model needs to incorporate mixed discrete phase boundary conditions, including reflection boundary conditions, capture boundary conditions, From Figure 1, it can be seen that the additional forces acting on particles mainly include suspension force, virtual mass force, pressure gradient force, thermal swimming force, Saffman lift, and Basset force. The calculation of suspension force is shown in Equation (3) [19].…”
