Adaptive control of contrast agent microbubbles for shell parameter identification

J Acoust Soc Am. 2012 Apr;131(4):2579-86. doi: 10.1121/1.3689555.

Abstract

An adaptive controller design is proposed and simulated for parameter identification and oscillation control in microbubble systems. Lyapunov's direct method and a Lyapunov-like analysis are used to show stability and convergence of trajectory tracking and parameter adaptation. The method allows for the determination of microbubble contrast agent shell thickness or material parameters in a nondestructive manner.
