Estudo de sistemas de suspensão magnética

Abstract

The objective of this presented work is the study of the techniques of control to stabilize a system of magnetic suspension with one freedom degree. First, the developed model was in an open loop. Forward, the model had applied techniques of control, like root locus with PD (proportional and derivative), root locus with lead, and, lead with frequency response. Through these methods, the model studying considers an open and closed loop. For this aim, it is necessary the study and understanding of this model, its components, and, the parameters to be analyzed. Based on this, the analyses and simulations of the model is given by the stability of the system, Bode diagram, also, the performance of the control techniques. Finally, the MATLAB® has given all the simulation and analyses. The results demonstrate that the PD and Lead control by root locus technique showed a satisfactory established control, otherwise the Lead control by frequency response technique showed a marginal stability for the system.
