Suppressing Chaos for a Magnetically Levitated Ball System
抑制磁浮球系統的渾沌運動
並列摘要
This study verified chaos motion of a magnetically levitated ball suspended and then elucidated a system for chaotic control. The detailed dynamic behaviors are numerically investigated by means of Poincare maps, phase portraits, time responses and frequency spectra. The results reveal that, due to the realistic nonlinear characteristics of magnetic forces, period-doubling bifurcation has been observed that lead to chaos. The largest Lyapunov exponent analysis is also used to identify the onset of chaotic motion. Finally, a technique for effectively controlling a chaotic magnetic levitation system will be offered. It involves employing an external input, called a dither signal, to the system. Some simulation results are presented to demonstrate the feasibility of the developed approach.
