Quenching chaos of a magnetically levitated system based on dither signals

作者：

Highlights：

• The rich dynamic behaviors are observed completely in the bifurcation diagram.

• Period-doubling bifurcations route to chaos.

• Largest Lyapunov exponent analysis is used to identify the onset of chaotic motion.

• Dither signals are applied to effectively suppress chaotic motion.
