Intelligent controlling microbubble radial oscillations by using Slave–Master Feedback control

作者：

Highlights：

• Dynamic of radial oscillations of encapsulated microbubble have been studied.

• A method based on Slave–Master Feedback to suppress unstable radial oscillations is introduced.

• Mean Lyapunov exponent theory is applied in stability analysis.

• Based on the obtained outcome acoustic pressure amplitude is one of most important factors in stability of the microbubble.
