Modelling, identification and control of a "magnetic levitation ce152"

Abstract EN

This project takes a comprehensive look at model development for a laboratory magnetic levitation with the final aim to design a control system is presented.

The CE152 made by Hum soft is a laboratory magnetic levitation system designed for studying system dynamics and control engineering principles.

First, the magnetic levitation system set-up is depicted, then the whole system is disassembled into simpler subsystems, then theoretical modeling is systematically described.

Identification of the necessary parameters is tackled using direct and indirect measurement methods and their results are presented.

As the system is nonlinear and unstable, it should be linearized at optional operating point and a digital PID controller with fine-tuned parameters is designed to track a small varying input signals.

Finally the simulation’s model is validated with the real system, the results show the simulation’s model is adequately represents the real magnetic levitation system.
